What episode does duncan come back???

Duncan returns in episode 13 I See London...
He comes back at the end and that is where Gwen and Duncan share their first Kiss (even though it looks like they have done it before XD).
Duncan is then on Team CIRRRH and he is put in the competition. He is competing in episode 14 Greece's Pieces. I believe their is going to be thêm GxD moments and kisses. I'm looking phía trước, chuyển tiếp to it!!!!! :D

he retunrs in episode 13 I see Luân Đôn at the very end but he offically is back in the game in Greeces Pieces episode 14

Most likely the episode "Greeces pieces", episode 14 [I think it's 14... XD]
