Rene is involved in a thread with Adrian Tudor Varias (Sin) on his journal, here. This thread pre-dates the thread with Cassidy by at least a year, which means it is taking place in a parallel dimension, with parallel dimension Sin.

Rene's first post -

Rene was in a good mood, and eager to be in an even better one. He swung into one of the non-tourist bars: darker, older, no neon, and well-worn. He winked at the owner/bartender, Delfeayo, and got a fond smile in return. He intended to check out all the patrons, see all his choices, but he was immediately drawn to a dark haired man, sitting at the bar. There was something about him. He pricked at Rene's empathy. Rene approached him, silent as an assassin, graceful as a thief, and slid onto the seat next to him. He was a damn handsome devil too. "Hey, cher, I'm Rene. You havin' a good night?"
