What is the meaning of あいつはあいつで?

Question

I encountered the phrase in this line:

あいつはあいつで、きちんとバイトしているらしい。

I think I can intuit the general meaning but I was wondering if anyone had a full explanation.

Answer 1

「あいつはあいつで～～」 means "He ~~ in his own way."

As the word 「きちんと = "properly"」 may suggest,

"Pronoun X + は + Same Pronoun X + で"

expresses the speaker's opinion that the Person X is doing something at least on a satisfactory level if not on an extraordinary level.

「これはこれでおいしい。」 = "This dish tastes OK if not spectacular." ==> "It tastes good in its own way."

One can also use a real personal name instead of a pronoun in this expression as in.

「スミスはスミスでちゃんと働{はたら}いている。」
