I was reading this and started thinking it was familiar... and then I got to the bit on the Room and went, "Yup, read this before, made me laugh."
"We've been roommates for over six years and NOW I find out you're a Trekkie?" <---for the record, that's a brilliant line, hehe
Keep writing!
Author's Response: Thanks. Glad to give you a laugh. It was over at Phoenixsong. Was hoping to find a new audience here. I think I'll enter that line into the "Best lines" collection here. I got some pretty rabid begging for more of this. I haven't really thought much on it, but I can see a "trapped in the Room of Requirement" fic building on this. All ideas are welcome, but I'm still not conviced on whether or not to continue. Thanks for reading.
