Two of Finn's children, Layla and Jodie, turn up on his doorstep. Finn and Allie have trouble looking after them both, so Allie calls in the rest of her family to help her out. Finn takes them all back to Byzantium, his bar, and they all have fun making cocktails and other drinks. Unknown to anyone, the two children put alcohol in their drinks. Mia shows up just as this is happening, and sees it happen, but keeps it to herself. The two children become sick, and Finn is worried that their mother won't let him see them again because of his bad fathering. (thetvdb.com)
