Jace from Shadowhunters is like the worst cockblock ever. He always ruins the best couple, Malec, whenever they try to get some action.
Jace interrupts Magnus and Alec's makeout session with a stupid sword fight.
He shows up at their party and starts a fight just to be annoying.
He texts Magnus like, 'Hey, Alec is here, and he's not my brother.'
