Everyone who dismissed Really Small Problems as filler better apologize right now.
...And lbr even without this callback it isn’t filler because RSP is an important landmark in Luz and King’s friendship in which he learns to treat her as someone with her own life, and not a toy to keep to himself. Kinda like what the Collector realized this episode in regards to King himself, how the roles have reversed as he teaches to a to a younger sibling what he once learned as one!
