Vision: And it wields me. It gave me sentience, and I give it bass drops.
Scarlet Witch: How can you use something that you don't understand? Infinity Stones contain incredible power. They're as ancient as the universe. Thanos wants them for a reason.
Vision: He can't have the Mind Stone. I'm still using it.
Post-Action

Vision: I'm afraid I cannot understand forces that do not adhere to the laws of science. But if you require my assistance, you need only ask.
