Do you really have to say "かれ" (3rd person pronoun) here?


The context is that _A_ , _B_ , and _C_ just got home. They are now wandering
around a big house looking for a group of kids. The 3 are wondering if the
kids have been studying. _A_ has not yet talked with _C_ :

> [line 1]「本当ですか？勉強していますか？」A-さんはたずねた。「証拠は？」  
>  [line 2] 「C-さんが見ました」B-さんはいった。「勉強していると **かれが** いうなら、それが立派な証拠だと思いますが」

Part of line #2 reads:

> ...勉強していると **かれが** いうなら...

Because " **かれ** " is obviously _C_ , do you really have to say " **かれ** "?  
If you do not say " **かれ** ", how does it change the nuance?




In this context, it would make little to no sense if 「かれ（が）」 were not said.

B-さん is saying that if it were C-さん(← かれ) who says that he saw the kids
studying, it would be a highly trustworthy source of information. It is almost
like saying "if the information came from C-さん **_of all people_** ".

In other words, the fact that the witness is C-さん this time is being the
condition for B-さん to call it a good proof that the kids are studying.
