Mantis takes a deep breath and lets it out very slowly. An intentionally open mind read differently from one that was unwitting or actively resistant. He saw the offered image and heard the scattering of thoughts right behind it, but that thing...in the back... His hands move out slowly away from his sides. He doesn't need the Hymn here, not unless he really wanted to reach back to find out what that void truly was.

"You're German? No, Dutch. Siebren de Kuiper. Kuiper Belt." He laughs quietly at the name. Mantis's gaze is unfocused as he speaks. It's a lot of concentration to get a clear string of information. "You pictured a shiny apple with the peel coming off of it in one go. And that...thing. You internalized some aspect of gravity? Like a black hole, but inside you. A lab accident. It happens to the best of people, but you control it now."

The mental chatter is too much, though, to bear for long. When Mantis draws back, it's slow and he breathes heavily for a few seconds after.
