Yeah, I would have eaten the whole thing also...and maybe a couple of the fingers of anyone else reaching for it.
I noticed on your grill there looks like a bristle from your grill brush laying between the grates. Caution for all. These bristles do occasionally come off the brush. Specially when the brush starts aging. Try to brush them off, blow them off, or pick them off. You don't want your food grabbing it and then transferring it to your mouth.
