Quote ColorAzure: I didn't read the spoilers, but from what it looked like to me was a zoom-in on Adam as Dylan is saying the baby's blindless disorder. But that could've just been a pan-focus on Adam, not necessarily him overhearing anything. Usually when characters overhear something, it doesn't zoom in on their faces like that.
Also, it looks to me from the 'next episode' clips that Chelsea has yet ANOTHER dream of Adam barging in and taking the baby from her.
Adam definitely overheard the conversation, and he beat it to Chelsea's door! He KNOWS the baby's his and I guarantee he's gonna fight for his Peanut! Dylan's name might be on the birth certificate, but it's a false one, and CAN be changed to reflect the real parent, after Adam provides medical and DNA proof that he's the daddy. I don't like Chelsea and don't want Chadam together, but I want Adam to have his baby; from the interview I read, this is gonna be a battle royal that will last for a loooooooooong time!
