Hey, you never know!
*sigh* I feel awesome after watching this episode thrice (yes, that IS a word, actually!) and I have some thoughts!
-First off, I think I KNOW where Lillith escaped to after she fled, to anyone who watched Heroes this monday! She developed a russian accent and went undercover as Danko's girlfriend! Hah! I'm sure that was the same actress, I just don't know where to look for the names of guest appearences on shows... but I'm quite sure it's the same actress!
-DINER SCENE: Kripke’s. Hollow. Diner. *giggles* That is all. And the fake fight scene? Yeah, still hurt as much as a real fight scene. When Dean says ‘Like that can’t happen’ to the fiery demonic passion with Lillith... It took me two viewings of the episode to get what he meant… That Sam told Dean about the events in IKWYDLS. Theeeen the line hit home. He does seem to like shoving the ‘Sam sleeps with monsters’ line in his face.
- But the brothers seemed to kind of be back this episode! The laundry scene, and the scene where Sam is prohibited from doing research, and Dean suggest that he watch porn. *chortles* It felt like season 2 again...
-I loved that scene so much, when Chuck got to speak with Sam about his powers. It's great because Sam needed to talk to someone who understood what he was going through so bad (ASIDE from Ruby!) and Dean (or anyone else for that matter) doesn't know what he has to do to get stronger. Funny how even when talking to probably the only other person who knew what he was going through who says it was surely wrong to do what he was doing, Sam denies it and says that "no, its fine it can't be bad". He's denying how out of control the whole thing could become. I'm really gunning for that blood-addicted thing right about now. Poor Sam.
-DEAN OF YORE WAS BACK! If only partially, he was baaaack! He seemed much more... animated this episode. He was getting angry, getting excited, making an active descision to stay with Sam even though Sam didn't wana leave, trying to pump up Chuck to come with him, getting p**sed at angels + God... it was so awesome!
-I love how Angels can change prophecy/destiny. They’re not supposed to interfere, but when they do, everything changes. It’s like the ‘agents of fate’ are also the ones that can alter it. But they’re not supposed to. Hence Chuck’s “I didn’t write this!”. Which makes me wonder if angels like Anna, who probably wouldn’t give a cr*p about prophecy/destiny, could change some of the awful and angsty things destiny surely has in plan for our boys. Ooo, or Cas! He could help too! Like he did this episode! YEAH HE SO SHOULD! Because sly!Castiel is turning out to be my favorite flavor of Castiel.
-CHUCK'S VISION:
What did he see!?! I was thinking apocalypse before, but I think the Winchesters already know about that, why would he need to warn them, exactly? Plus, his visions seem to come pretty close to when stuff happens, so now I'm thinking character death? A phi on Zachariah for not allowing Chuck to warn them!

grr...
...Ohmygosh that was long...
