Ulrich is not a jerk! Geesh... Johnny is so clueless and STUPID, so he doesn't know when to stop following Yumi. Whats up with him asking Yumi to marry him... can you say... OBSESSED. *twitchety twitch twitch*
Ugh. Ulrich was a jerk here, Jeremy, Yumi, and even Ulrich himself said so. Johnny is annoying, but you can't deny that Ulrich was responsible for him getting a big role in this episode and it was all just for his personal pleasure (at the expense of Yumi's and ours.)
Look, Ulrich's no bad guy but he does have flaws and that especially showed in this episode. Denying that is sort of like missing the point entirely.
And whilst I don't care for Johnny either, no-one seems to be giving him credit for telling the Principal and Jim about her. If he hadn't, she wouldn't have got put on that hospital equipment and might have died before the RTTP was initiated. At least let's thank the lil' twit for that.
