I'm fine with them having known each other longest.  It kinda of suggests that they probably joined the caravan to they valley around the same time, maybe with Seras on the payroll to make sure she gets there in one piece.  Either way, they've had some time to get accustomed to one another.<br/><br/>As for whether or not their relationship has moved to the carnal, I'm a little split.  I'm open to it, but I think Seras's initial move would be to deflect.  You know, kind of a "How am I to keep you safe, away from my arms and tangled in you bedroll?" response, but not a hard rejection.  I'm not sure if Yulia is the sort to try and brush that sort of thing aside (she's got the confidence and the body, she could probably roll over Seras's defenses on that front), or if she'd rather tease and leave things at a simmer until they're "someplace safe" to to broach the subject again.<br/><br/>Of course, the Bar Guest is "someplace safe", everybody was clean and fed, it might've come up again depending on how tired people were.  Could've used some Invisibility to sneak a rendezvous depending on the sleeping situation.  Either way, we've confirmed she didn't get a chance to prepare spells last night.<br/><br/>Essentially, I'm pliable on the subject, future or past.
