Hm. He's always around, you know. I started to play around with an XF/Alias crossover yesterday, but I don't know if it's going anywhere.

I think that the nastiness really struck me in "Traders in Snow." He's a complete bastard there, although you know, most of it is just to mask his own vulnerabilities. But I think if I'd continued that story, Marita and Scully would have banded together to get rid of him.
