Unless a third season is announced, the show is over, correct? Don't lynch me (yet), I have a point to all this!
The last episode is, fittingly, Last Train to Gloomsville. And while obviously it was all "The End", it had a sense of closure. These guys are such good friends they've won an award for it. There's some stuff left hanging, but that's the nature of this show. But in part two, look at the moment when they hug. Closure. Ruby runs straight for him (she's not shy anymore) and throws her arms around him. Without hesitating, Skull Boy hugs her back. He definately likes her back, and he's certainly not holding back. Of course, this is in front of their friends. No one likes being caught doing something sappy with their crush while friends are watching. So they react with nervousness.
(On a much less serious note, anyone read "Ruby Gloom's Guide to Friendship"? Ruby describes her friends in detail, with the exception of Misery, who didn't exist then. Skull Boy's page is hilarious. I'll quote it.
"Skully!
He's sooo cute! When we met it was a classic story of boy meets girl, and then boy runs away from girl." There's more, and the whole page is covered in hearts. Half the book has her fawning over him. Seriously, what doubt is there left?)
Ummm... sorry. This was a long post, and did exactly what I didn't want to do, analyse the show. I'll shut up now and go back to reviewing...
