-But. Tracer is a lesbian, why would she have backpack full of condoms??
-In the Rio 2016 Olympics, the IOC distributed 450,000 condoms for the 11,000 athletes living in the Olympic Village. That's about 42 per athlete -regardless of whether they needed to use it or not! 0_0;;;
That set a new record from any previous Olympics, but since Overwatch takes place in the future, perhaps a higher record was set and even more were handed out to the athletes? XD
Anyway, Tracer wasn't carrying them in her backpack. Widow basically walked past and dumped a whole bunch into her backpack before Tracer could stuff her Union Jack flag into it. And Tracer is basically " (Um. Why why would you do this? Are you telling me something Ms. French Gymnast? ..Do I need to clear something up with you? ;;;) In the end, it's simply trolling between two athletes from rival countries.
(And tbh there are ways that even Tracer could use them if she wanted to. But I'll just leave that part to the commenters! AA Be safe & responsible!)
