I Should've Seen this Coming

A follow-up to my fic "I Fully Support this Badass Babe". Lainey Lewis is touring with her cover band and a (newly) single Barry wants to see her. Unsure if she wants to see him, Barry creates a ruse to get his heavily pregnant sister to go with him. Erica then invites Adam to join them thinking they're going out for a "Spa Siblings" day. What could possibly go wrong?
