Whether or not Courtney's behavior was "in-character" for how she's acted previously, her personality in Sundae Muddy Sundae still contradicted everything they'd been doing with her all season and throwing away a plot that makes 95% of the whole season entirely pointless.

What happened to Dave wasn't "Development", it was a rare case of a character being Flanderized/DERAILED (and YES, I will use that word) within their debut season all for the sake of a weak subversion of the usual couples outcome that only ends up making most of the season completely pointless just like Gwentney's implosion in All-Stars did!
