I have been reading a book titled "the Female Persuasion." There is a phrase with a infinitive be-verb, which I am curious about why "be" should be instead of am.
"I wasn't supposed to be here at Ryland, actually. It was all a big mistake, but it happened, and it isn't fixable."
"Is that right?" he asked. "You were supposed to be at another college?"
"Yes. Somewhere much better."
"Oh yeah? Where is that?"
He laughed. "That's a good one." "I was," she said. Then, more indignantly, "I got in."
"Sure you did"
I did. But it didn't work out, and it's too complicated to go into. So here I be."
"Here you be," Darren Tinzler said.
Why in the bold text is "here I be" used instead of "here I am"? Just to emphasize it?
