hah, good guess, but i don't think Ausiello pays a lot of attention to CSI these days. besides, Sara's pregnancy wouldn't be THAT shoking, since she is happily married. or would it? she is kind of the last person you imagine having a kid when you think of it.
on the other hand, it would be a great way to bring Grissom back for an ep and let Sara leave the show under the pretext of pregnancy. yeah, i could see it happening. don't think it will, though. i'm giving it a 10% chance that Ausiello is talking about Grissom and Sara.
ETA: just read the tips more carefully and the father of the baby is suppossed to be unknown at first. i give it 1% this is a fake trail and he is talking about Sara.
Maybe it was [for an explanation] to talk about his return as GRISSOM and her SARA and him, were discussing the show. I wasn't there, just an assumption, one never knows what the stars are doing. They have gone to see each other in their perspective plays, their friends, and a phone call LOL.. But, I hardly think they just chatted about abused animals. I, on the GSR and the baby thing don't know, but he's [WP] doing a play till May when the season ends, unless they've filmed an episode before he started. On one site a girl [who lives in Vegas] said she saw him and LF in Vegas, filming out in the desert, so soon will fnd out what's true and what isn't.
