When Ruthie (Mackenzie Rosman) makes an inappropriate comment at the airport on the way home from Scotland, airport security takes Eric (Stephen Collins), Annie (Catherine Hicks) and Ruthie in for questioning. Meanwhile, as a favor to his best friend Martin (Tyler Hoechlin, who does not appear in the episode), Mac (guest star Kyle Searles) pays a visit to Sandy (Haylie Duff) to find out whether she is still interested in Simon. Lucy (Beverley Mitchell) does her best to stay positive about Eric's condition, while those around her are terrified of losing him. Finally, T-Bone (Colton James), Jane (Sarah Mason) and Margaret (Andrea Morris) -- with lots of help from Sam and David (Nikolas and Lorenzo Brino) -- plan a big welcome home for Eric.
