The Eldritch Knight fighter's Weapon Bond feature (PHB, p. 75) says:
At 3rd level, you learn a ritual that creates a magical bond between yourself and one weapon. [...] If it is on the same plane of existence, you can summon that weapon as a bonus action on your turn, causing it to teleport instantly to your hand.
Edward the Eldritch Knight has a Weapon Bond with a net.
Edward's net has restrained a goblin. Edward has walked some distance away from the goblin.
What happens when Edward summons his net; is the goblin freed, or does the net arrive with the goblin still in it?
