Bruce doesn't trust him in Batman Beyond's Meltdown (VERY good episode, I recommend it) because of the whole revenge theme and the fact the Bruce has been through this whole villain reformation thing before with Riddler, Ivy, Harley, Penguin (to an extent), etc...Arnold Wesker is the only one out of Batman's rougues who actually seriously went sane.
The beef I have is that in Sub-Zero, you kind of get a bittersweet "The End" feel. Victor is out there, but he's just glad that Nora's safe now. There's kind of a disconnect between the end of Sub-Zero and the start of "Cold Comfort."
