The answer to this question depends largely on whether or not I'm still married in the Buffyverse! ;D
Aaactually, it doesn't change my answer too much... Just different reasonings behind it, I guess, so I'll answer with those. XP
And I know I'm totally cheating, but I blame all of you who posted before me. Initially I'd just planned on cheating a little by saying I'd like to double date with Willow and Oz. But then CHz was talkin' about Faith and her 'free spirit' (let's just call it that)... Girl could really show a fun time! ...I'm not talkin' gettin' jumped; I just mean wild and crazy antics in general ([HASHTAG]#scoutsHonor[/HASHTAG]). Then someone mentioned Anya, which gosh, Anya and I would either LOVE or HATE each other. My husband oftentimes pats me endearingly (mockingly) when Anya does/says things that we know I do ([HASHTAG]#tactfail[/HASHTAG]). Come to think of it, our Buffyverse kinship would have to be with Xander and Anya because it so closely represents us (not when they get all depressy later on, just the fun part of their deal). I wouldn't so much like to one-on-one with Anya, but if we could arrange a double date there, I'd dig it. And, well, there's Spike... But like I said, I'M MARRIED. XD And, to be honest, while Spike OOZES sex appeal, his accent is knee-weakening, and his sense of humor is the one I probably most appreciate, he's not really my type. Not long termy like anyway... Okay, so maybe if it was a one night 'hang out'. Totally kidding. XP
Good thing my husband's not on these boards. He'd kick my butt. 😛
