Quote Tily4life: I think it's Hilary.
Hilary will probably turn out to be Neil's lovechild with Rose, who will turn out to be a woman from his past before he met Drucila. Hilary will be angry at being the forgotten child, blah blah blah, so she's targeting his kids and girlfriend via the gossip blog in order to hurt Neil. Maybe she should hook up with Adam and they can compare notes about their abandonment issues.
I think so too, only it seemed odd that we didn't get to see Neil's gift from Lily. She said she knew he would want a copy of the picture he lost on the usb stick. I am thinking that the picture was of Dru. Dru just seems to be suggested a lot lately.
