[The scene opens in an eerily quiet part of a ruined cityscape, where Tracer is cautiously exploring the area. Suddenly she pauses, her pulse pistols at the ready as the sound of gentle footsteps echoes nearby. A figure appearing to be Mercy walks into view, her movements slightly more stiff than one would expect.] Tracer: (surprised but cautious) Doc? Angela, is that you? What in the world are you doing out here all on your own? 'Mercy': (In an almost perfect imitation of Mercy's voice, but with a slight off-timbre) Oh, Lena. I was looking for you. We need to regroup; it's dangerous out here. Tracer: (squinting her eyes suspiciously but smiles) Always lookin' out for others. Right, let's find the others then. They must be worried sick. 'Mercy': (nods) Indeed. I was concerned, too. But you seem to be doing... remarkably well. Tracer: (laughs softly) That's 'cause I've got the best guardian angel, haven't I? But hey, something's off. Why haven't you asked me how I'm feeling? The real Mercy never misses a chance to play doc. 'Mercy': (pauses for a fraction longer than natural) Of course. How remiss of me. Lena, how are you feeling? Any injuries I should be aware of? Tracer: (smirking) Oh, I'm tip-top. Though, I did have the strangest dream about tea. (laughs) You know me, even dreaming about a good brew. 'Mercy': (slight hesitation but recovers quickly) Tea is good for the soul. I'm glad you've been keeping up with your hydration. Tracer: (laughs, but her voice takes on a sharper edge) Always. So, speaking of brews, remember that time in Cairo? With the shopkeeper and the pink kettle? You have to admit, that was hilarious! 'Mercy': (appears slightly confused but masks it with a smile) Yes, of course. The pink kettle. How... humorous. Tracer: (suddenly serious) The real Mercy wasn't there, "Angela". She was on a mission in Nepal. Who are you really? ['Mercy' suddenly drops the facade, its form shimmering and twisting into an otherworldly creature that snarls at being exposed.] Creature: (in a distorted voice) You are too clever for your own good. I thought I could deceive you completely. Tracer: (grinning defiantly) Well, you'll have to try harder than that to fool a member of Overwatch. Now let's see how you handle this! [Tracer's form blurs with her trademark speed, as she unleashes her pulse pistols in a controlled, precise burst. The creature attempts to morph and dodge, but Tracer's disorienting speed makes her a hard target to track. In a dance of blinks and gunfire, Tracer manages to outmaneuver the creature.] Creature: (screaming in pain) You cannot... destroy me... Tracer: (firmly) On the contrary. As my friend would say, "Heroes never die!" Too bad you're no hero. [Her guns deliver one final, fatal round, and the creature collapses in a heap on the ground, defeated. In a flash, the body dissolves into the air, leaving no trace of its former existence. Tracer looks around to ensure there's no immediate threat before activating her comm.] Tracer: (into her comm) Overwatch, this is Tracer. I've dealt with a shapeshifter here; might be more of them. Keep your eyes peeled, and don't trust anyone too quickly. Now, where's the real Angela? [The scene ends as Tracer scouts the area, remaining on high alert for any other threats that might be lurking in the shadows.]

[The scene opens with Tracer casually sitting at a quaint cafe's outdoor table, sunlight sprawling over cobblestone streets. An "Angela" steps into the light, her white coat and honey-gold hair identifiably Mercy's as she approaches the table.] Tracer: (raises an eyebrow but smiles warmly) Angela! What brings you to this neck of the woods? 'Mercy': (smiling, with a slightly forced warmth) Hello, Lena. I thought it would be nice to take a break and catch up. Perhaps a cup of tea? Tracer: (grinning) You read my mind! The question is: Earl Grey or Chamomile? [Mercy sits down opposite Tracer, her back perfectly straight, casting a faint shadow that somehow seems out of place.] 'Mercy': (delicately) Earl Grey sounds lovely. [Tracer nods to the waiter, ordering. She taps her foot lightly in a seemingly random pattern, but in reality, she's sending a distress signal through her chronal accelerator.] Tracer: So, doc, how've you been? Anything new at the field hospital? 'Mercy': (a little too quickly) Everything is running smoothly as per usual. But let's talk about you. How is the fieldwork? Tracer: Oh, the usual flashy runs and blinky stuff. (laughs) But maybe you'd care to join on the next op? Could use someone of your talents. 'Mercy': (slightly tilts head) Join you? I... suppose it could be arranged. [Tracer's eyes hone in on the gesture, the mental gears turning. Something is off.] Tracer: (excitedly) Speaking of which, remember that time you patched me up mid-mission in King's Row? You removed a bullet with one hand! Still amazed by that. 'Mercy': (hesitates for a fraction of a second) Yes, multitasking is essential in our line of work. Tracer: (playfully, unfolding a napkin) True, true. And I know you're not one for reminders, but your birthday's coming up. Should we throw a surprise party with those funny hats you love? 'Mercy': (brief flicker of confusion before fake enthusiasm) Hats? Oh, quite right. I do enjoy a good surprise. Tracer: (eyes narrow almost imperceptibly) Yeah, surprise parties and funny hats, they're the best... except you hate surprises, always said they were disorganized--Isn't that right, Angela? [The impostor's facade cracks, eyes widening with realization as she stares at Tracer, who glances to her side. Backup has arrived, with Overwatch agents subtly encircling the vicinity.] 'Mercy': (voice waivers) Lena, I am sure we can-- Tracer: (interrupting, firm and clear) Sorry, love, but the only appointment you've got is with justice. Overwatch, secure the area and keep those eyes peeled! [Overwatch agents move in as the false Mercy attempts an escape, only to be caught by the encroaching agents. In a blur of action, the impostor is contained.] Tracer: (standing up, holstering her pistols) Nice try, but you can't fake a big heart. That's something only the real doc has got. [Confident the threat has been neutralized for the time being, Tracer smiles with relief as agents make the area secure. The real Mercy would have to hear about this one.]
