hrm. it's been a while since i've seen it...you mean what happened on the game station because he left it without an exit strategy? if so, then yeah, that's one of the VERY few times we've seen him own up to one of his mistakes. but he hasn't done it at all in his tenth incarnation, afaicr, and it pisses me off that rtd was reportedly going to put a little nod in 'last of the time lords' re: the doctor's moment of pique costing the planet one-tenth of its people and britain its golden age, but didn't.

what i'm really hoping to see in the finale - not holding my breath, mind, but it would be awesome - is something like what happened in the sandman: the kindly ones...ie, ten FINALLY starts to realize that his 'no second chances' approach is doing more harm than good, or that this incarnation really has some fatal flaws which he's blinded to, and that for the good of everyone involved, a change is definitely in order. 'maybe donna's right - i DO need to change' etc. five had a revelatory moment like that when tegan left at the end of 'resurrection of the daleks', so it would be nicely in keeping with the history of the show...only, you know, much more dramatic since this would involve the doctor literally changing himself to help everyone.
