I agree that Cain didnt want to help moria with Holly, and now he wants her to turn her back on her other child to be there for his baby. Adam as a young man has a life to live, likewise the baby has got a lot of support to look after him in the future. Most mother's would not want their child to ruin thier own life to hide such a crime, Cain is being his usual selfcentered dipstick.
