I don't play Tracer much but I was messing around and got this voiceline today and I'm.. yeah
Any CRUMB I get from the Slipstream lore I will happily munch up are you kidding me. This also supports my headcanon that Mercy was one of the head doctors in charge of her case, probably leading or near the top of a team of medical doctors, researchers, quantum physicists, etc. Not only was Lena facing the effects of chronal disassociation, but she was also dealing with the physical aspect of being lost in Time for 6 months 2 years.
This included things like:
-Extreme emaciation
-Extreme sensitivity to light/noise/texture/taste etc etc
-Muscle weakness, resulting in difficulties standing
-Speech and language difficulties, including being entirely nonverbal for the first three weeks
-Psychological effects, nightmares, extreme paranoia, constant fight/flight state, extreme distrust
-Several more I haven't found the words yet for
So her team had to contend with all of that, plus Lena actively fighting any kind of procedure/testing that they needed. Hair, skin, blood, urine samples were all critical to discovering if whatever she had was contagious, if there were any other illnesses that they had to content with, but Lena would actively fight them. Screaming, pulling away, hiding on the other side of the chamber away from the access point, she would do anything to avoid the masked figures behind that glass.
This team would have been very impactful in ensuring she received the care that she needed. It's a debt she'll never get to repay to them, but she tries, every day.
