[ castiel's far from innocent when it comes to going overboard with power, he and sam share that failing, and the cost that came with it. it's a weighty enough reminder of their own hubris and the harm they can do with the best of intentions. here, the playing field is somewhat more even, at least between the Displaced, and it's really almost quaint, to be back in this training abilities stage, usually only reserved for Jack these days.

the fact they're woefully under-prepared for the threats they're facing aside, it's sort of refreshing to have the old team back at figurative square one, learning how to fight, doing the training montage. the part where cas actually knows what a training montage is now marks how far they've come. ]

Perhaps. [ distracted, and despite the fact he just passed on having a beer, cas picks up the growler, examining it while he speaks, and ends up pouring a sip's worth into the spare glass to test it, curiosity getting the best of him. ] Our powers advance and expand over time, and with use, in this world. I'm sure you'll graduate from ice pack quickly, Sam.

[ maybe this buffer, the lack of immunity to the cold, is a limitation that'll keep him from advancing too quickly. weird to think of the glow inside their chest as conscious of its host's safety, but they hardly know what this thing is, let alone it's level of autonomy. ]

Dean, at least, will be thrilled with your abilities.

[ sam chilling his beers for him? yeah, that's sure to come up some time. ]
