I think it was more a case of them processing things. Plus not having the emotionally bond to Connor Angel has they wanted to get all the facts first. Fred especially was strong in her belief that Wesley wouldn't do it without good reason. I guess Wes not sharing his research with anybody is maybe the one thing I don't get about his actions.I dont get why Fred and Gunn werent more angry with Wes. He betrayed Angel in an unforgiveable way, but also he didnt share any of his research with them. He didnt ask them to help him find out what was really happening. In a way he was unbelieveably arrogant. He assumed he'd read the prophercy right, he assumed he had it all figured out. No matter how noble his intentions were, he was wrong and selfish not to confide in them. I can completely understand Angel's reaction to him in the hospital room.
I've not missed Cordy being in the last few episodes and I feel bad about that
