Answer troll. (As Rose) ([1])
Form:
What John learns:
Heeeee totally pretended to be Rose on her pesterchum handle. And he was definitely throwing out movie references left and right there, and he had a basic clue about time shenanigans, but that's about it. So basically, he's kind of annoyed that now he gets that he should really get the references that Dave keeps throwing out (HE LIKES MOVIES, WHY CAN'T HE REMEMBER THESE THINGS HE LIKES, THIS SHOULD BE EASY).
This memory is likely to make him annoyed after the game. Because it is such a reminder that he's amnesiac, and has to play games like this, and will tangentially remind him of Dave and he's mad at Dave.
Form:
Memories come in the form of a miniature goblet, with a slightly less miniature glass vial. Fill the goblet and drink to receive your memory. (Three uses worth of poison liquid in the vial.)
