> A: あの番組を見ましたか。  
>  B: いいえ。見ようとしたら、息子が友達を連れて帰って **来たんです** 。

I only know of ～て来る as an indicator that someone goes to do something and then
returns, for example:

> ちょっとたばこを買って来ます。

But recently my textbook has used this construction in several sentences where
this semantics doesn't seem to fit perfectly. I don't know, what would you
make out of this sentence above? It doesn't seem to make sense to me to say
that someone "returns and then returns".
