I’m starting to think that the next A that will be revealed will possibly be Wren.

• Wren was engaged to Melissa, so besides Toby, he is also very familiar with the Hastings house, meaning he would have known how to get in the house to trap Spencer in the shower without Melissa seeing him.
• “Get steamy with Wren, get steamy with me. -A” can be taken literally.
• Wren has access to Radley, and I find it a little weird that Mona called him to help with Spencer’s break down.
• If he is on the A Team, it would be easy for him to get Toby a fake Radley badge/ID.
• Wren is the one that was with Melissa when Ian’s body was found. We know that he was helping Melissa get drugs for “Ian,” since he worked at the hospital, but maybe he was the one sending Melissa the texts pretending to be Ian all along. After re-watching that episode, he just didn’t seem as shocked as someone should be after a body is found.
• Melissa told Spencer in tonight’s episode “Hot Water,” that no company was better than bad company. Why exactly is she calling him bad company? Is there something more that we don’t know about Wren?
• From the season 3 finale notes, we know that he will have something to do with a death in Rosewood, and he will be appearing in a different light at the same time.
• Hanna also finds a major clue in Wren’s office at Radley in the season 3 finale. Why would a major clue be in Wren’s office if he wasn’t somehow involved?

I’m sure that there has been more clues along the way, but this is just what I can think of right now. Thoughts?
