I think Wren is AD/Uber A. Firstly, because in 1×04 A wrote “Nosey bitches die”. Pll is American so they spell it as nosy. Wren is British so he would spell it as nosey. Secondly, in 5×19 Aria had a problem in her maths test which was solve A. People have solved it and the answer is W R E N. WREN!! Finally, Wren is a bird and what print have the liars been wearing season 3-7? Bird print!! Search up “Pll bird print” if you don’t believe me!!
