Can anyone catch me up on The Secret Life of the American Teenager, REALLY quickly?

Question

I missed last week's episode, and a new one is about to come on. can anyone tell me what happened last week? just the main points, so i'm not completely lost

Answer 1

well basically, amy's grandma came down, and the family discoverd she had Alzheimers. So it was decided that Amy would stay with her mom after all. Adrian is also trying to find out who her real dad is, and she gets her birth certificate, and meanwhile, Ricky is trying to get more involed with the baby, and tries to find out Amy's number

Answer 2

yeah, and amy's 2 friends, i forget their names, get in to a fight over who ricky would rather have s*x with, or "seduce" and the read-head is now going out with the other one's older brother.
