After Seth teleported, the vines grew from the ground and encapsulated him. He didn't travel far enough and was caught up in both the blast from the negative energy and Aries' unique skill.
Since the Radius of the negative explosion was around 50- miles and Aries' following explosion was around 100- miles, there was no way for him to escape it within the time given. Even if he used Greater Teleportation EX once, it will merely teleport him close to 3 miles which he also couldn't do for he was also low on Mp.
