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).
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.
