Thinking about the almost canon shadowbug where Wildbow confirmed that if Taylor didn't join the undersiders and stayed an independent hero, Shadow stalker would have ended up as her weird psudomentor. I'm pretty sure he said they wouldn't have ever got that close, but imagine how insane it would have been if they did.
Any secret identity romance where you actually hate each other fucks, and I can't even decide who it would be funny to figure out the other's identity first. I mean it's only so long until Sophia invites Taylor AND emma on one of her solo patrols.
Or maybe Taylor horribly internalizes sophia's predator and prey mentality and ends up with some crazy split where she likes being skitter but hates being Taylor, almost completely separating the two with her insane compartmentalization.
I can't see it going anyway other than terribly, and I would have loved to see it.
