So that's how they met. [pepe:0]
Something more must have happened between them if this Volk leader is so obsessed with Ruce. Honestly, even if Ruce and Red deal with this psycho, I don't think that during the war or after it both could live happily and peacefully somewhere. Ruce was shaped by the military and family into a government machine. In turn, Red has become such a symbol of a warrior of the anti-volks coalition. Either they will fake their deaths in some way, or they will retire in gratitude for their service. Although imo the first seems more likely.
