( dean takes the opal back as soon as cas is done and returns his pocket for safekeeping. he's not about to let anyone else get their grubby hands on it, save for sam and jo. this is something they need to keep between the four of them for now.

but there's something in his eyes, the way they light up at the mention of the lab, that seems to say: we're doing this. at least, once the boys are better armed, because if there's one thing dean has actually paid heed to its cas' warning not to venture out into the woods without decent protection. he may generally have a death wish on most occasions, but he's not an idiot. )

Well, now you're just begging me to ask. ( which he will. eventually. he flashes cas a suggestive smile, but then it's right back to the topic at hand. )

This give you any better idea on how to find it? The lab. Or any idea what the fuck she's doing with nukes?
