Adrian and Jackson
The way they were (still) standing - with Jackson pressed against his back, and Adrian leaning into him - was not the most subtle, although they had each witnessed far more obvious PDA in their houses and at the previous Hogsmeade weekend. Adrian was not normally one for any kind of display, but he guessed it made Jackson feel better.
"You do realize that is not reassuring? It is the Gryffindor insane courage that puts you at risk." Adrian pointed out. Indeed, it was not a comfortable thought, Jackson trying to protect him and getting hurt for his effort.
