It’s from the PLL finale promo
He comes back in a very surprising way; in a way that I don’t think the character Wren was expecting to come back. Thus, his presence is a mystery to us. It’s really not going to be until the final episode of the series that an explanation for what he’s doing here is revealed and it will be a whopper. It will not be what you see coming. He doesn’t really have a lot of screen time. We see him just once or twice in the second half of the season, and then we see him in a very surprising exchange in the final episode, which will be the moment that really causes people’s heads to explode in a positive way. He’s part of the ultimate final twist in the final episode.
Way to ruin it dude. So he won’t be A.D then?
