As Matilda approaches, she'll find that there's one more strange thing about Ten's presence: He's wearing the ugliest most touristy button-up shirt with palm trees, boats, waves, and suns on it. So when she holds him at rapier-point, he just glances up at her and slowly blinks through all ten of his eyes one at a time.

There's a soft boop from the phone in his hand as a stylus moves around in his blob of a hand holding it. A moment later he turns the phone, holding it and the message on its screen up towards Matilda so she can read it:

"What are you talking about?"

Because, uh, Matilda, what are you talking about? Ten's just trying to relax and enjoy his tea.
