Back in the World

Garret Dillahunt takes over the role of Sam Taggert's ex-husband Steve Curtis, previously played by Cole Hauser.

Character Susan Lewis states that Chuny is "stuck on the I-90." This is not a term used anywhere outside California. Most of the US does not refer to their highways and interstates as "The (highway name). It's just "I-90" or "I-55" unlike in California where they say "He's on the 5" or "the 710" etc. Since the show is written in CA and filmed in CA, this has been a common mistake throughout the series.
