Of course he's meddlesome. [He grins, though it doesn't quite meet his eyes.] …Tadashi was also really meddlesome when he was alive. [And still is, come to think of it.] I think he purposefully programmed him that way. Eventually you just learn to deal with having a large, squeaky shadow.

It is my job to assist. [Baymax, polite as ever, interrupts and looks down at Hiro and Leon.] Tadashi designed me to help at all costs.

Buuut a promise is a promise. I'll keep him from "meddling" with you.
