Jack collapsed last episode and his three dads are all panicky about how to help. Castiel tries to use his angelic abilities, but he has no idea what is wrong with Jack or how to fix him
In desperation they take him to a hospital, desperately trying to get through his admissions process when he has no surname, family or officially presence. But medical technology also doesn’t work so well with an ailing Nephilim.
Running out of options, with lots of powerful grief and Dean especially falling apart, they turn to Rowena
I always love a visit from Rowena! She isn’t thrilled about helping a nephilim and especially not the son of Satan - thinking that anything to do with satan is better off dead. But she can’t resist Jack’s innocent charm, even if he does kind of accept she may be right
But even Rowena’s magic doesn’t work. She does diagnose him though - a Nephilim needs grace to live. An Archangel Nephilim needs archangel grace. Which is a problem because all the archangels are dead.
Everyone starts brain storming except Jack - who wants to spend some time living and asks Dean to take him out. Which includes Dean showing him how to drive. Yes, drive his car, his baby; he doesn’t even let Sam do that. I like that a series of 14 seasons can have moments like this that have been so well established - and I like that they didn’t feel the need to make that point in this episode. We have fourteen seasons already we don’t need to make this clear.
They also fish with Jack being all gushy about this because he wants to spend more time with dean while he still has time left
And this whole scene, whole arc, is beautiful - but why Dean? There’s Sam and Castiel saying how hard it is to lose a son, and how this hurts more than their previous losses - but even they are talking about how it hurts Dean especially. I think the habit of Supernatural to focus more on Dean than the others takes something from the show. Especially this where Jack has, if anything, been closer to Sam and even closer to Castiel than Dean.
Castiel thought he had managed to track down Sergei, a shaman, who may be able to help - but only seems to exacerbate the problem. Castiel is duly enraged
But they now have no hope for Jack
