I like Scourge much better than selfish Doc also. Scourge's talks about how he doesn't really feel anymore and about his faint memories of his last lover are more compelling than Doc whining about not being famous.
This would be a perfect opening for Scourge to rediscover his feelings ,with the female Jedi Knight. And the comments about him training the children would fit in nicely also. A Jedi knight falling for a Sith Lord, could be a fun story.
