What is なって in 本物っぽいなって


At the beginning of the movie "Your Name", there is a scene where Taki is
waking up in Mitsuha's body, and comments "すげー本物っぽいなって".

What is the meaning of なって in this phrase?

Is this supposed to be て-form of なる, and he is commenting "they became like
the real thing"?

Or is it some informal なあ..って that just describes his wonderment? Or yet
something else?




It's a sentence-end な followed by a quotative-って.

> すげー本物っぽいなって  
>  (I was thinking) this looks so real.

Without this って (and the implied verb 思ってた), this sentence doesn't work as a
response to her(his?) sister.

なる ("to become") is not relevant because なる **must** be preceded by the ku-
form (連用形) of an adjective (or adjective-like auxiliary).
