That all supports what I said, right? If almost everyone has almost all of their language functionality lateralized to one side of the brain then you'd have at most one inner monologue.
(At least) two minds: yes. Two inner monologues: no.
So if like me you have an interior dialogue, which is speaking and which is listening or is it the same one? I do not ascribe the speaker or listener to a lobe, but whatever the language and comprehension centre(s) is(are), it can do both at the same time.
Same half. My understanding is that in split brain patients, it looks like the one half has extremely limited ability to parse language and no ability to create it.

You have two minds (at least). One happens to be dominant.
