As Wilkinson pursued him and interfered with his Dimensional Gate, Vaughn used a perfected Lumos Charm to reveal and strike at Wilkinson’s hidden presence.

• Donald collapsed after Wilkinson’s appearance overwhelmed his ability to process what he saw, while Vaughn’s Occlumency let him perceive Wilkinson as a shifting mass of pixels.
• Vaughn and Wilkinson exchanged questions, and Vaughn deduced that Wilkinson was a projection because he produced no visible light or heat; Wilkinson praised Vaughn’s unusual spells and said he had first noticed him through Essex.

• Vaughn realized Wilkinson was one of multiple people using the name DeSantis and concluded that their different appearances and simultaneous activities came from sharing an identity.
