Scene of Angela parents

I feel this scene is important because of two things. One being that Swenson is getting into the fact that Angela might have been lying about her parents now because her “step”  dad seems to know everything about her since she was little. “ back when she first learned, i got her a computer”  to me seems like he has been around when Angela says he was dead. Another thing is i sense Swensons nervousness in the room asking questions because he doesn’t want to sound like a creep or maybe even the character of her story but come to find out Angela might has encountered things as so at her middle school.
