forgot to add. if I was ALexis I would strangle Olivia!! who is she to allow minor kids to check into her hotel, play the "cool" mom with someone else's teenagers and give them a little Pep speech?
first no birth control is 100% sure. second, sex IS a big deal. it wasn't so long ago Molly was trying to choose between rafe and TJ (well, sorta). either way, she and TJ were broken up, he slept with someone else.
I think ALexis can handle "the talk" with her own daughter, (thank you very much) without "help" from Olivia. Olivia had a responsibility to let ALexis know. just because Olivia is currently sleeping with Molly's father doesn't make her Molly's "mother figure".
