かわりもしますよ what is the meaning of this も?


I usually do not ask a question here unless after trying multiple times I am
still stumped and admit defeat.

I understand that かわりもしない would mean "has not changed even a single bit"
putting emphasize on the verb as part of the negative, but I do not know the
meaning of this も in a positive.

For now I tentatively understand かわりもします here to mean either "he has
definitely changed" (ie, emphasis) or "he has changed, among other things"
(meaning of 'also' implying other things in addition) but I don't know which
or if it's something else altogether.

This type of も does not mean "also". In this case, it adds the nuance of "of
course", "it's only natural" or "it's no wonder". It is used with something
that describes a reason or a cause.

  * 昨日から何も食べてないの？ そりゃ、お腹 **も** 空くよ。
  * 昨日から何も食べてないの？ そりゃ、お腹が空き **も** するよ。
  * 全く連絡がないんだから、心配 **も** しますよ。
  * たった1000円なら、流石に買え **も** しますよ。(=買えますよ)
  * そんなに悪く言われたんじゃ、彼 **も** 怒るわけだよ／彼が怒り **も** するわけだよ。

In this manga, the reason part is added after the result part.

I could not pinpoint the specific definition in monolingual dictionaries, but
basically this should be related to "exclamatory-も" or "も to make the sentence
sound reserved". This も is used to vaguely describe "how things turn out
naturally".
