Finnley came over for ALL the pictures and probably took like...an embarrassing amount. Of Charlie, of Finn, Finn and Charlie together, her and Finnley, Charlie with Diego and Grace and the kids and Finn. ANY AND ALL COMBINATION. She will get all of them developed. Even the really terrible ones. She was basically like an overly proud mama. She might've brought her something sparkly to wear like a necklace or earrings as a prom present, because Finnley thinks any occasion is a good occasion to spoil her baby sister.
And as a courtesy to Charlie, she did NOT volunteer to Chaperone. ;)
