I also loved the scenes with Kendall and Greenlee (and Ryan and Ethan had some pretty good lines, too)! I just hated the pompous way that Ryan was acting before he realized that Greenlee was absolutely serious and sure that Kendall had not tried to hurt her. He always jumps to conclusions - especially where Kendall is concerned. He did it with Zach and Ethan, too........wait until he finds out that the "villain" is his own, jerky brother!
I agree that they are not trying to gather fan sympathy for Jonathan. They probably just wanted to remind us of his "backstory" to sort of "explain" why he would be violent with another person (not just slapping Maggie, but shooting Ryan and trying to poison Greenlee, too), and also to contrast that with Ryan's childhood experiences (ie: why Ryan "didn't turn out the way" that Jonathan apparently has). I'm sure that he will be carted off to jail, as soon as the truth about everything comes out. I loved Reggie's trying to protect Maggie, though! But Jonathan's creepy responses about Maggie's waking up, going to sleep, and doing everything in between with HIM, and how Reggie and her friends can "see her sometimes", but she's "moved on" and only exists for HIM, etc., were very telling - and probably indicative of the sort of controlling / abusive behavior that happens in real abuse and battery situations.
On a happier note, as much as I used to be an Edmund and Maria fan, I have to say that I agreed with what Zach was saying - about her honoring her marriage more than her marriage was honoring her, at this point. Every time Ed-dumb sees Maria, he berates her, insults her, and otherwise thwarts her attempts at reconciliation - what is it going to take for her to leave that smug, self-satisfied, feeling-sorry-for-himself, jerk and just take the kids an run off with Zach, already???? (I was afraid - the other day when Zach proposed to Erica that the 2 of them team up to find Babe and Jamie - that they were hinting at starting a romance between the 2 of THEM, thus ruining Erica and Jack's chances for happiness YET AGAIN! But hopefully Maria will come to her senses and get together with Zach, so that won't happen!)
And Anita and Aidan were very cute..........I wonder if it's weird for Aidan to be courting the sister of his former lover, though????
And Reggie and Danielle were very cute, too........I agree that she will probably say "no" to spending the night with him, though. Or she will and nothing will "happen", but Livia and Derek will think that something DID "happen", then she'll be grounded and not allowed to see Reggie any more.....and they'll have a "Romeo and Juliet"-type situation again, where they have to sneak off to see one another.......
It would just be nice to see everyone happy at the same time, for just a few episodes, anyway!
