After a failed ult and your team dying, you decided it was the best to quietly go back the way y'all came from. After all, you couldn't do much as a support anyway against a full team.

They knew you didn't die, but they didn't bother to look for you. Well, except for one, and that was Doomfist, as he wanted all dead. You hid at the first place you could manage, refilling your heals and ammo, unaware that he was coming.
