When I saw that it was Buckner/Ross-Leming writing this episode, I groaned but...I didn't find it as bad as I was expecting it to be. I mean, there were some things that bugged me, but I guess ever since 12x02 I've been keeping my expectations down in the toilet, lol
The main story of this episode seemed to be something like "Crowley's family sucks." ;) The whole story about Gavin's love Fiona's spirit being attached to an object, plus the thing about the ship just vaguely reminded me of Red Sky at Morning from season 3. They did weave a few new bits of info into this one, such as the scenes between Crowley and Lucifer. Lucifer's son is out there waiting to be born, Lucifer is aware of it and is apparently planning to turn the tables on Crowley, as well as unleashing some can of whoop-ass (along with the kid). I guess we will have to wait and see where that will lead.
I liked Gavin a bit, even though we didn't really get to see much of him, certainly not more than 2 episodes worth. Maybe it's because I find Theo Devaney kind of cute and I like the accent, lol...so I did feel a bit bad when he was going to go to his death to be with his girl and stop those killings from happening. It does show how different he was from his dad and grandmother. Speaking of which, why was Crowley so reluctant to have Gavin do that? He still wanted him to live as normal a life as possible? Rowena is in it for revenge of course, after Crowley killed Oscar.
As for Mary...I know this has been said before, but I am not liking what she's doing with the British MOL, and especially the way she is lying to the boys. I was glad that she did show up at the bunker at the end and came clean to them about what she was doing...but part of me still wonders about her motives...I dunno. Is she going to get them to team up with the British MOL more in order to stop whatever big bad they'll have to contend with (such as Lucifer & Lucifer Junior)?
And then there is that random demon girl Dagon? Something like that...Who rescues Kelly. "Come with me if you want to live." That Terminator line had me rolling my eyes. Gah. Anyway, who exactly is she working for? Lucifer? Crowley? On her own? Maybe I missed something...
So, this one wasn't as bad as I was expecting (though again I think the bar has been set pretty low), though it seemed like there was a lot jam-packed into it at times. I liked that they found room for the classic rock at the end, though that song's been used before, hasn't it? Like in the season 6 finale when Sam's wall crumbled? Guess I shouldn't complain, though, with the real lack of music lately anyway.
