[Donatello does a full body shudder.] Ew. Ew, gross, no. Karai is Shredder's daughter, and my Leo had a big crush on her before things got ugly, so never talk about that again.

[Eugh, of all things, envisioning being related to Karai might break him.

But Leo is touching him, which means he's probably worried. Stay focused, Donny. He needs you. Don't think about anything other than the task right in front of you.

Donatello smiles, patting him on the shoulder before moving away towards the living room. He's gotta do something, and right now he's surveying the space. Alright, he'll need to get another futon, of course, and definitely more food, and he should probably whip up something so they can track each other across distances...]

If I just took people's word for it when they said I couldn't do something, I wouldn't have gotten anywhere. What do you like to eat? And what do you usually like to live with, besides a bed? Do you at least do daily meditations? [He's a child. Donatello doesn't even consciously decide that he has to take a much more active role than usual taking care of this brother. It's just a given.]
