[Jessie can't see it, but Venkman scrubs at his face with his free hand. He lets out a ragged sigh, and when he speaks his tone is apologetic.]

I don't think you've told me that much about your home. I know there's four of you toys here- and I met one of 'em earlier this month. The cowboy. Haven't had the pleasure of meeting the others.

[Derailing? Yes. But Venkman's genuinely curious, and maybe switching gears and talking about Jessie can help. Maybe he can cling to memories of other people better than his own.

And maybe talking about her own life will keep Jessie's mind off of worrying about him, for at least a minute.]
