Megabyte and Bob vs Hexadecimal
It's a little strange that despite her constant presence in the first two seasons there were only two episodes where Hex was the big bad problem they had to deal with. And in both cases Megabyte was eliminated from the equation near the start.
Seeing as how Hexadecimal was an enemy of them both and that she and Megabyte were supposed to be constantly feuding, was anyone else a little disappointed that they never had an episode where Bob and Megabyte were forced to team up to stop her? I recall they were forced to team up against the User once, but Hex almost seems like she'd be a more likely opponent to force them together to put aside their differences.
I remember watching Painted Window and thinking it would be more interesting Megabyte got to contribute to defeating her for once.
