Nate's mom might revel that she has a soul, but for now ... HATE!

Like every other adult on this show, I'm guessing Nate's mum has some kind of ... deep-rooted psychological reason for being the way she is. Probably Daddy-issues, or something. She keeps reminding me of the Anne Hathaway in Brokeback Mountain (so now I keep expecting Nate's Dad to end up secretly gay, or something, but that's already been done with Blair's dad. And yeah, I think it's totally awesome that Blair's mum knows he's gay, lets him have his secret life and STILL wants him in her life. It makes me totally sad.)

Plus, he seems to have a fairly good (for the Upper East side) relationship with his Dad so their wouldn't have been DRAMA!!!!!

You know what would have been awesome? During the chaos going on for every other family in the show, to cut to Chuck and his Dad sitting around the table for like 2 seconds, eating dinner, completely calm and friendly and oblivious to any turmoil outside.

Or perhaps just asleep/stoned/drunk/out of commission in the arms of two women for the entire episode. Just as an explanation. I like missed Chuck.
