DON'T READ ON IF YOU HAVEN'T READ BREE TANNER YET.
Okay so when Bree goes back to the house before Diego and Riley, she sees a pile of ashes on the floor.
So then when Riley gets home she says everyone was there but Diego.
So who was the vampire that was burned then?
It couldn't have been Diego could it have been?
I mean, unless Riley somehow got back before Bree..?
