A funeral-goer says to Robin, "I hear you're a woman who can get things." And she replies, "I've been known to locate certain items from time to time." This is a reference to the exchange between Red and Andy Dufresne in The Shawshank Redemption (1994).
First appearance of Ray Wise as Robin's father, Robin Sr. Previously he was portrayed by Eric Braeden.
Eric Braeden was supposed to play Robins father Robin Sr in this episode but pulled out at the last minute saying that exhaustion from his role on The Young and the Restless kept him from doing the role. That did not go over well with some of the cast and Neil Patrick Harris called him a d-bag on Twitter.
Danny Strong who plays Trey in this episode also starred with Alyson Hannigan in Buffy The Vampire Slayer as Jonathan.
The pill that Robin gives Lily is most likely Adderall. Adderall is a stimulant prescribed for the treatment of ADHD and can cause people to feel energetic and invigorated. Robin also tells Lily to stay hydrated, which is a known side effect of Adderall.
