sentences:  However, Liz finds out that Pete and Paula are having an "affair" where they sneak around and use her apartment for trysts that include silk scarves and Pop-Tarts; Pete tells her that he and his wife got pregnant almost immediately after they began dating and have never had an exciting romantic/sexual life because of that, so they have found this way to spark their marriage.With his role of Liz's confidant increasingly filled by Jack Donaghy, Pete played increasingly reduced roles as the series continued, although his marital woes and inability to catch a break were increasingly mined for humor.Jack pities Pete for his aimlessness and unattractive appearance, and occasionally attempts to boost his confidence, beginning by convincing him to wear a wig for a week in "Tracy Does Conan."
