Fuck no. Unlike “Merry Christmas Mordecai” or “Dumped at the Altar,” that was actually a nice way to shake up drama and the status quo after Mordo finally won the girl he’d been pining for since Season 1. It also showed that there was more to her than being the love interest, and it allowed CJ to return.
Mordo and CJ had immediate chemistry, so I really don’t get why the RS Crew thought it’d be worth it to use her as a hot-headed plot device yet again. If they really wanted to touch upon the idea of having lingering feelings for an ex, the writers could’ve made CJ a little more understanding/forgiving, and Margaret could’ve just remained a friend. But nope; they used both the Christmas episode AND the wedding episode to make Mordecai push her away again.
Fuck JG and fuck romantic plots that go nowhere. Even AT pulled this off better by having Finn gradually accept how much he blew it with FP.
