When you watch Marry Me Season 1 Episode 3, you'll find Jake and Annie going head to head with a annoying mom, Julie, in their building. Annie is determined to put on a haunted house, but she and Jake get much more than they bargained for when a kid refuses to leave. Annie tells Jake she hates Julie so much because she envies her in some way. Jake tells Annie she'll be a great mom. After returning the kid to his mom, which turns out to be Julie, Annie realizes that she has nothing to worry about, and she'll make a great mom when the time comes. Meanwhile, Gil and Kay spy on his ex-wife, Cassie, while trick-or-treating. Eventually, Gil realizes that Cassie hasn't moved on with her life completely either.
