Elliot and Olivia were questioning the parents at the Busken Group Counseling Center of disabled and mentally-challenged children. Afterwards, Olivia was talking about the case in her own version/theories until realizing that Elliot's mind is elsewhere.
Olivia: How's Kathy?
Elliot: Over 40 and having a baby. Just can't stop thinking about all the bad things that can happen.
Olivia: So why don't you see a Doctor?
Elliot: We're Catholic, maybe it's better not to know.
