Help understanding this line


The two parts of this line I'm not quite sure I understand is the meaning of
来てる and who is being referred to in 体あったまってきた.

Looking at this
[website](http://maggiesensei.com/2010/09/04/slang-%E3%82%AD%E3%83%86%E3%82%8B-%E3%82%A4%E3%81%A3%E3%81%A1%E3%82%83%E3%81%A3%E3%81%A6%E3%82%8Bkiteru-

Is this similar to the instructor telling the instructee that they are
"nailing it"?

My second question is I am unsure who of You/I/We is being said when the
instructor says 体あったまってきたよ is there something obvious that makes it clear who
is being referred to?

Instructor「あーもう！ このポンコツが！ちゃんと妾の言う通りにせんかー！虎だ！ お前は虎になるのだー！」

Instructee「がおー！」

Instructor「 **おっ、いいよ！ 来てる来てる！体あったまってきたよ！ ワンモアセッ！** 」

Your own reference says it’s someone _about to be_ something. In this case,
the instructor has just told the instructee to "become a tiger." The
instructee growls, indicating some kind of effort to obey. So the sensible
interpretation is that the instructor thinks the instructee is _on the verge
of_ becoming a tiger. It even works when interpreted literally as the tiger
"is coming."

To me, it’s obvious from the context, the meaning and the lack of an explicit
subject change. So before the part in question, you have the instructor saying
(roughly) "almost there", and afterward saying "do it one more time" (meaning,
try becoming a tiger again). Both of those are clearly directed at the
instructee. So, since there’s nothing to indicate otherwise, it stands to
reason the part between them is the same. That part means "(one’s) body has
gotten warm," which sounds like a physical sign of the instructee’s imminent
success in becoming a tiger. Thus the instructor would be referring to the
instructee’s body.
