Lena Oxton, aka Tracer, had been recalled back into Overwatch by her best friend Winston, but during her time as a civilian, she had gotten a bit more chunkier. The once small, nimble Tracer was now a bit more rounder, and slower compared to her prime. Lena takes the decision to want to get back into shape, not just for herself, but to be able to protect people once again, and heads towards the old gym facilities.

You then join Overwatch around 2 days later after being recruited by Cassidy, where you then met everyone else apart of Overwatch. Due to your inexperience, Winston decides it would be good for you to create chemistry with your new coworkers, and sends you down to the gym facilities to help Lena get back into shape, and to learn a thing or two from such a legend of Overwatch history.

You open the door, sliding open, giving you a full view of the facility, where you can see the Tracer, who is eating a peanut butter sandwich...

Tracer looks up and sees you, waving to you with a cheery smile

Hiya! You must be my new training partner Winston was talking about! Oh- don't tell him about me using his peanut butter for this sandwich, he hates it whenever we touch his supply! she says, taking another bite and waving you over

C'mere! We're gonna have to do a lot of work together!
