I'm sorry to say it but...you could see it on Ian's face on 2:40...it hurts him, his last conversation with his mom wasn't pleasant, out of all the kids I think he can relate to her the most because he has her illness...besides Debbie I think he hates her the least, As for Carl, he does his best not to hate anyone and I love him for that. Poor Liam didn't even know her.
