Albus Dumbledore watched the house burned, while the fireman try to extinguish the fire. Petunia and Vernon body is burned. Dudley body is injured, but still alive. Harry Potter dead. His burned body is lying beside Petunia and Vernon.
Albus Dumbledore stood there for another 5 second, before he apparate back to Hogwarts school of witchcraft and wizardy and inform Agusta Longbottom that her Grandson is the boy who lived.
Maybe Longbottom will be a better pawn.
