Seriously, if he cared at all what they thought of him, he'd be more than a bit put out about the lack of gratitude. Leela figures out going behind Darkel's guards is a good idea, and she's the greatest thing since sliced bread. He manages to rig a barrier between them and the guards using nothing more than Matrix access and a single terminal, and he gets no thanks whatsoever.

...okay, so maybe he is a little bitter.
