Overwatch - New Team Mom

Isn't she is more like a grandma?

I’d say, for Overwatch it goes like this:
Soldier 76: The Dad
Mercy: The Mom
Reinhardt: Grandpa
Ana: Grandma
D.Va: Bratty overconfident younger sibling
Torbjorn: That slightly weird but cool uncle who gives you something awesome on your birthday provided you don’t tell your parents
