Safe with You
That said, one of my absolute favourite things about the universe of Buffy and Angel has been, since its first appearance in season five, Spike's love for Dawn.
They haven't spent much time together since season six, and the scene in 7.02 "Beneath You" of Dawn threatening Spike was somewhat satisfying (I mean, really; you go, Dawnie!) but it totally broke my heart, too.
So, Spike ditching two big battles (and potential Apocalypses) to take care of his sick Little Bit?
Holy sheesh, y'all! I'm smiling idiotically now, I might cry later. I seriously lack the emotional maturity to handle my excitement over this. And, look, he's holding her hand! Do you understand that this is the single greatest thing the series could have given me?
I may ship Spuffy and Spuffel and Spangel and Tillow and several other ships that lack the convenient portmanteau names, making them too unwieldy to add here, but at at the end of the day, Spike and Dawn are by far and wide my favourite duo of the series (which, by default, kind of makes them my favourite fictional duo, full-stop.)
(Oh, and, uh, who totally called this Dawn-plot? I so got this.)
