I'm having having trouble with this trophy, have done it twice through most of the game with someone but it won't pop. So I looked at a walkthrough & it said that it won't happen if your companion already has the trophy! Can anybody confirm or deny this? Both times I did it it was with someone in white robes with the embroidery so it is a possibility.
Re flying, I know you can tandem fly by pinging but every time I do it, I fall cause I'm not pressing X, & then am too far away from the other player. What am I doing wrong? I'm sure I p*** off other players because of this.
Edit: Never mind about the flying, just figured out that you can also use the shoulder buttons for flying & thus be able to press O at the same time. Could have sworn I had already tried that!!
