Yeah pretty much this ^^^. Honestly i felt deans first death just felt off but after that he's not really around, always on his own in the greenhouse, so i just never thought about him that much. Untill his reaction to seeing dave bleeding out just being a 'found you' and out of all the sprites grizz has he chose a blank neutral one. Just made me actually pay attention to where dean has been up to that point and he's too much of a question mark, i honestly can't say with confidence what he's been up to.
