Tamaki watches Doll's ever more defensive posture, her knuckles turning white as she grips her shirt. He knows this topic is suddenly distressing Doll, a lot more than he would have ever thought being called "pretty" would distress a girl, and he's not entirely sure what he should do. He doesn't want to take it back, that doesn't feel right, but he doesn't want to upset Doll anymore.

And then she says that: she only has one. Only has one eye? Did something happen to the other one?

Tamaki wants to ask, but he's not sure if it's really okay to now. He doesn't want to cause Doll anymore pain than this is causing her already. He wants to help, but he's not sure how.

He does the only thing that feels right: he reaches out, taking her hand and tugging it away from the shirt, to give him his own to grip on to instead. Then he reaches out his other hand and gently, very gently, lays it on her other arm.

"What's wrong?" He rubs his thumb against her skin, hoping it's soothing. "You can tell me what happened, if you want. I won't get mad or anything."

If Doll trusts him enough, he's willing to listen.
