They have a lot of voice lines in Overwatch 2 that imply that Hammond resents Winston for leaving him behind on Horizon. But sprays and prior lore indicates that they were close friends on Horizon.
Canonically speaking, I think both of them still don’t know the other is alive, but if they do meet up in the PvE … it’s probably safe to assume that Hammond will be bitter.
My question is, do you think they will eventually become friends again if the Junkers somehow get involved with Overwatch? What’s your opinion on how their story should be handled?
