Imagine Loki using you in Stuttgart as a hostage to keep the Avengers from following him. You hit him in the nose and he begins to bleed. Wanting to make an example of you, he tries to use the mind stone/sceptre on you to make you comply. It works for a moment, but it wears off almost instantly. Terrified that it doesn’t work on you, Loki teleports you both away. He’s now determined to find out why it didn’t work.
