は as sentence final particle


I meant to gather more examples before posting this question, but here we go.
These are some lines out of various Ghibli movies I saw last weekend.

[code]

    わからないは - when asked to take a guess about something
    いないは - after looking for someone in a specific place
    
[/code]

I realize this is casual and may not be strictly grammatically correct. Still
I wonder what's the reasoning behind these type of sentences. It's not
difficult to understand what they mean, but why は? How would a native speaker
justify the particle? And if someone can tie it to some formally correct
version of the sentences that would be great!




As a sentence-final particle, it's `わ`, not `は`. See more about in
