Pharah likes to stay home with you. She’s a hard working woman, so after a long day, she’d rather have a nice dinner with you at your place.
Sombra will take you to an arcade. Not just with electronic games, but also with other things like skee ball. She sometimes subtly hacks them too, just to make it easier for you to play because the longer you play, the harder it gets – and it gets hard.
Tracer would rather walk around in London. There’s something about the city that makes her love walking around with you. She’d often end up seeing something she thinks you’d like and well, it’s better to pull her away from the store.
Mei would like to stay home and watch a movie. She loves spending private time with you and cuddling with you while watching a movie.
Widowmaker is very distant, after what Talon did. But she enjoys to spend her time in silence. A library or a park would be the best spot for her.
D.Va would obviously rather stay inside and play videogames with you.
Zarya likes to sport, train, go to a gym etc. So, sometimes she’d invite you along and maybe have some dinner afterwards. She makes sure you’re having a good time, though. ‘Cause if you aren’t, she’ll leave with you immediately.
Ana would, just like her daughter, stay home. She’d rather read something in silence with you by her side, than spend time together in a loud, noisy place.
Mercy is a busy woman, so dates with her would often be ordering takeout and brining it to her infirmary. But it’s really nice! She appreciates it and both of you can catch up on what happened.
Symmetra always tries to make sure you’re happy. There’d be joking insults but they’re quite funny. Dates with her could occur anywhere, as long as it’s a nice (and preferably clean) place.
