Sheldon asking the pastor for a "signed liability waiver" before getting into the baptismal pool. Missy shoving him in anyway is the sibling energy we live for.
This isn't an action-packed episode. There are no exploding rockets or trips to the university. Instead, it is a quiet (and sometimes loud) family argument about belief, belonging, and stubbornness.
