I didn't mention it before, but during the "So awesome" strip, I was thinking she was a wee bit over-dressed for a sparring match.
Granted, that only helps my theory of "Sparring = Deniable First date". Granted, that may be a 'junk; shirt, but the Bracelet and earings? Somehow I doubt that is standard combat wear for the elves that have been in 'kill em dead' fights.
Edit: Something about the last panel struck me as something we've seen before, and after some archive trawling, I found what it reminded me of.
This older comic has very similar stances and positions of one Elf who is in a cryingly bad mood, and one stone cold killer who's last name is Amraphel. Going to show you, that if you want something bad enough, you can find supporting evidence anywhere. Hell, they even have the same general shots. Panel of Elf on her hands and knees, shot of the crying face, then the outline shot. Then a few quite beat panels, then hot elf sex. Still, don't see Misa going for that, and highly doubt she'll try and brain-fuck Sara if something does happen.
Plus, if Misa tried to do a grapple with Sara, she'd be likely to be thrown into a wall. Sara is likely to have been caught offguard by the 'wounded foe' trick before.
