vic's best memory could be when dinah finally convinced him that jackie wanted him to take care of her, the idea that maybe he could raise a kid. except that it didn't really work out that way.
maybe that year in canada, some nebulous moment when he finally felt like he was getting what richard was trying to teach him.

there are a lot of contenders for worst memories! jackie dying, walking out on helena, and he still has nightmares about being locked in the box when he was little.

in game his best memory was realizing he could suddenly breathe again. his worst was probably meeting a helena only to realize she's someone else entirely.
