( tl;dr: Back in the museum of Vas Captio [and yes, it looks identical to the one the other incarnations of Vas folk would have known] , Sam and Shannon Winchester start to have an awkward dual apology session when an earthquake strikes, collapsing the roof of the museum in on them, knocking a display case onto Sam and rendering him unconscious while impaling Shannon with a broken floorboard. Shannon has an asthma attack while reviving Sam and picking glass out of his clothes and hair and Sam pulls the broken floorboard out of Shannon's side while she applies pressure and he plucks out splinters. They share their first kiss, relieved that they both survived it and he helps her out of the rubble and onto the road before telling her he has to go find his brother and Andy and she has to stay awake and keep pressure on her wound. )
