This is becoming comfortable to her. She has no right to feel this way, but she feels safe when Deku carries her. It's easier to be this way.

"All right. I'll try to get it's attention. Brace yourself."

She feels warm whenever she uses her powers like this. It's kind of like how her eyes heat up when she uses her powers in her normal body. Either way, it takes a few seconds, but it's not that long before anyone who can notice Deku probably will notice Deku.

(If she remembered her life, she'd wonder how Momo dealt with this.)
