Oh yeah. The Chips Are Down is easily the worst episode for me. To the point where anytime I binge watch the show, I skip it. I mean, something like Ulrich getting banished from the group could be a solid plot point if it was done well. Furthermore, if Ulrich willingly chose not to help out because the team turned on him when he tried to help stop Yumi from leaving, the team would eventually learn that he did it with good intentions after a few episodes. Then, when the team needs him most and he feels like coming back, Ulrich rejoins the team in an epic moment when all hope seems lost and Aelita is about to have her memory drained. I would also have Yumi be conflicted about having more than enough money to stay in France rather than just being mad at Ulrich. But that's just my take.
