ER

Season 13

Season 13 was marked by many goodbyes, as well as a story arc with Forest Whitaker. Neela and Gates hooked up, and John Stamos became a series regular, but Kerry Weaver left to work in TV in Florida, Shane West left in the season finale after his character lost both legs,... more and even Luka left to care for his ailing father. Guest stars included Sean Young and Stanley Tucci. The standout of Season 13 was watching to see how the infamously prickly Abby would react to her surprise wedding, orchestrated by Luka, in "I Don't."
