Quote Jake Austin: she answered nick and she answered michael 2 so WTF?
Phyllis did not hesitate one bit when she saw on the caller ID that it was Jack. That is all I am pointing out. Her voice sounded somewhat happy when she said "Jack". She knows she can run to him just like Sharon can run to Brad. However, Phyllis and Jack were in a long lasting relationshipm not just a romp-a-room like Sharon and Brad in the hotel.
See, that is what should have happened with the whole Phick thing. Left it at an affair and move on. That's what Sharon and Brad did. A mistake is a mistake. But Phyllis had to go and get pregnant. That is called not being responsible. She hasn't heard of birth control.
Anyway, back on topic, it was the excitement in her voice when she answered Jack's phone call. Phack is back and so is Shick. Brad is just a confidant to Sharon, period.
