Like everyone makes jokes about Sombra hacking and checking search histories, but like she probably does.
She knows Tracer has an online shopping habit.
She knows Solider 76 has a habit of checking out dog memes on Facebook.
Reaper looks up cat vids.
Widowmaker? She googles her symptoms (Sombra is concerned).
She knows McCree just looks up the “what in ______” memes
She is actually concerned with what Mercy looks up. With Mercy typing the exact words “why does my team keeping dying and then blame me when I can’t fucking heal them” and “why does my team suck”, she feels threatened to go on a Mercy team.
And so much more. Fear her for she is god.
