When he growls, \"You crushed that girl!\" to Mitchum, it's a disgusting moment of privileged outrage. He can't believe that someone would deign to offend his granddaughter (who must be smart because she shares his genes). Had he listened to Lorelai when she explained how it all went down, he could have avoided this awkwardness and simply gossiped about the Huntzbergers behind their backs in true WASP fashion. Instead, he works himself up into a seething rage that he immediately transfers to Emily, who goes full Regina George on Shira. As Rory gives her thank you speech up on the stage, Emily claps wildly while Richard and his sad eyes stare on in \"wtf have I done\" disbelief.
