"Alright…" Lucien makes a sad expression as he opens the bathroom door slowly. "If you don't want it, I'll leave you alone."
Donna is too confused, frustrated, and mostly angry. She doesn't feel any anger at him but at herself. [What am I doing?!?! I just wish he'd ask us to do it, but I'm denying it myself!?]
[But how could I accept it that way?? How could I let my little brother help me bathe when we're both grown adults?? This can't end well!] She wonders.
She is going through the most significant internal struggle of her life, reason against feelings. She doesn't want to accept what she already feels for Lucien and mostly, do naughty things with him.
But because she really wants that, just like him, Donna can't let go of him. "Wait..."
Lucien clearly heard Donna, though she said that in a faint whisper. Yet, he doesn't move. "Do you really want it?"
