There's a pause as, firstly, the spider processes the full-on henshin she just missed. Like, poof, suddenly fabric? Man, she should've specified a theme song and some kind of space backdrop.

Next time, maybe. For now, secondly. She rights herself enough that she can align herself with one of the mirror columns in the carriage. Huh, they even got the halloween outfit part...

She turns. Lifts part of the dress, to inspect the lace, and one of the sleeves. Nods to herself, wipes away a figurative tear (ha, spiders don't cry!). She's definitely not sober enough to process the emotions currently running through her atrophied lil hermit brain, because the next thing she knows she's doing her spider best to give Crowley a hug.
