I'm confused on this picture. The question is, my teacher told me that

> 来ない時は(約束した日時または時間)
>
> 分かっておるであろうな(あなたはどうなるのか分かっているはずだ)

But I don't understand how can it change into this? I understand about the
translated version from my teacher now but when I was trying on translation on
the first time it went like this.

> "The time that you doesn't come, You're understand?" It's weird right?

But from my teacher, I can understand it now.

Except I don't know how to change `来ぬ時間` into `約束した時間`.

Is it some kind of grammar?

Especially `分かっておるであろうな` into `あなたはどうなるのか分かっているはずだ`

I can understand that わかっておる can translate into わかっている but It's followed by
であろうな.

What does it mean, and how can it turn into `あなたはどうなるのか分かっているはずだ`?

question
translation manga sentence
How should I understand 〜ぬ時は?
It's a good question. :)

> 来ない時は(約束した日時または時間)  
>  分かっておるであろうな(あなたはどうなるのか分かっているはずだ)

来ない時は is actually equivalent to a **_condition/premise_** ; **もし** 来なければ
**どうなるか**. どうなるか is only _implied_ , and continues to the question,
分かっているだろうな, which is to remind (you) what follows if (you) don't come, saying
it in an intimidating tone like an old sage.

It literally says:

「来ぬ時は」 (≂ 来ない時は) -- "When you don't come / If you don't show up..."  
「（どうなるか）分かっておるであろうな」 (≂ 分かっているだろうな) -- "I suppose you know (what will happen).
/ You know (what will happen), do you not?"

分かっておるであろうな, or 分かっているだろうな in modern/standard Japanese, is used as a _threat_
here: "You see what happens?" i.e. "You better not!" -- "You should come! (or
else...)" in this case.

The way the person speaks (来ぬ for 来ない, おるであろう for いるだろう) is the so-called
[老人語](https://ja.wikipedia.org/wiki/%E8%80%81%E4%BA%BA%E8%AA%9E) / old man's
speech in fiction, a kind of
[役割語](https://ja.wikipedia.org/wiki/%E5%BD%B9%E5%89%B2%E8%AA%9E) / role
language in fiction.
