"I envisioned a different future for us. Goodbye, Susan."

Kneeling in the dirt in another dimension, gritting her teeth, holding her breath, desperately trying to hold up her force field against the crushing weight of Victor's powers – this sort of thing was exactly why Sue had never tried to pursue a relationship with him.

Try to imply that maybe someone else could contribute a worthwhile idea? He burns all of Dad's consoles and runs off to his dingy apartment for a year. Consider sending astronauts – with space experience – to the newly accessible extra dimension for which they'd had to design environmental suits? He gets the team drunk and goes on a joyride to said other dimension, nearly getting himself and the team killed, getting himself left behind. Someone says the wrong thing to him once he comes back? He starts exploding heads and creates a wormhole to destroy the earth!

That kind of temper, and he wonders why, "he's always been alone." Sue thinks maybe he should have been dropped on his head as a child; maybe the sympathy hugs would have balanced him out and she wouldn't be running out of air in her flickering shield.
