During the scene where Harry, Asta, and Joseph are discussing the bomb Joseph mentions that the "Greys" have left him out of the plan for Earth. Harry says, "like when everyone is invited to a party except you". Asta counters with, "oh God, I thought you didn't want to go to Kayla's birthday". Harry then mispronounces Kayla's name as "Kaylala". Kaylala is the actual name of the actress who plays Asta's daughter Jay.
