Yes I would naturally make an excuse and leave and say I "forgot something",but the characters that I have seen play on Cats in years past (this is not pointing the finger at any current Catskills rp'er) are "super smart" and if my vamp didn't enter and made an excuse to leave. That character would automatically(magically) discover what my character is. Deus ex Machina,anyone?
You can't control what other characters can infer.
For the player to pretend the character knew it outright, in an absolute and undeniable sense, is foolish.
I fail to see, however, how you can get mad at a player for the character for making the inference. If he thought everyone who didn't enter his house was a vampire, the character would have other problems to deal with. Namely the fact that anyone who just didn't like him would think he was a vampire.
I actually seem to recall such a rumor spread about Galen once. If I'm remembering that right it's a good guess it was based on some similar incident.
I remember once, I tried to import what I found was a very, very awesome RP convention from Europa to LS: The use of a hooded robe as a disguise. At the very least, wearing the hooded robe, it was considered that the character was difficult to recognize.
When I returned to LS from Europa, I put in Galen's profile "hard to recognize when he wears his hooded robe." I figured, surely my fellow RPers would read a profile!
First person I encountered was a bad guy. "Hello, Galen."
Good guys don't have a monopoly on the god-moding you describe. No, you didn't say they did. But that was the implication. Or, at least, I thought it was. Was I wrong?
-Galen's player
PS: Lest I be accused of sanctifying myself, I'll relate an anecdote about myself, and let you draw your own conclusions: The closest I've come to god-moding, to my own recollection, did involve something a little similar. A character was under a gypsy curse, and I had long-played Galen as having a background with gypsies, so I decided he inferred what was going on, at least in highly general terms. The player who played the character who cast the curse went with it, and we got, I believe it was like 3 or 4 events out of it, and we collaborated on, something like 5 fictional posts? Whether she actually liked it or viewed it as god-moding I guess I'll never know for sure now. Damn I've been doing this for a long time....
PPS: And, on a semi-related note, I as delighted to see GL following a similar convention to Europa when it came to the hooded robes. And I was even more delighted to introduce that convention to non-RPers at a recent EM event.
