Anthony did his best to help people, and made good use of his Prefecty skills to try and get everyone in while maintaining some semblance of order amidst the chaos. Whether or not he did so... well, he probably didn't keep the order, but he made sure that as many people as possible got on and pulled Terry along with him, then dragged him into Cadi's compartment for likely awkwardsauce times.
Draco was meant to be helping the other Death Eaters, but only did so a bit before faking like he was more hurt than he really was, ducking onto the train, and going wherever Pansy was.
