Update :
The dispute was settled in their favor.
They have deleted their twitter account or have changed their name again? I'm not sure which. I did find a protected account with the original name minus the underscore, but it has no discerning links or icons at this time.  I have no proof it's the same person, but I'd be cautions of its potential to be the same person.
They do have a youtube account still but it looks like all of the video's were deleted except for 1 posted 1 day ago that just says "you dont know me"

Included screenshots of the closed dispute and the twitter accounts.

I no longer have access to the DM conversation on twitter.  She had not responded past the point screen shot point in my initial post.
I did take the advice of Rendrassa  and let them know they hold no rights to the artwork and are not allowed to use it in any regard unless payment is received in full.

All in all, my guess is this is now done.  I will be contacting paypal to see if they can offer further assistance but I believe my interaction with the client is now done from this point.

But definitely gather everything, and call paypal.  Do not use their automated system.  At the very least they can resolve the $20 fee, but there have been instances of them eating the chargeback entirely.

I contacted them after reading this.  I was informed that until the dispute is resolved with the bank we are unable to do anything and unfortunately paypal is unable to expedite the process since it is through the bank.  Time frame is 30-75 days depending on the steps paypal needs to take.  Looks like I'm in for a long haul run. 

If the charge-back is not decided in my favor I will contact paypal again to see if they are able to help me further, but until them it looks like here I sit. lol.

Thanks again.

Also please note that since this is a chargeback, not a claim, you will be hit with the $20 fee once it goes through.  Unfortunately, when there are two users of the account your chances of winning are zero, as it's likely been listed as fraud by the guardian.  Regardless of what payment processor you used, the banks will always resolve unauthorized use in favor of the account holder.

Thank you for the heads up.  I'll prepare my finances accordingly for this outcome.  I appreciate the information.

The reason you're seeing two emails is because Paypal allows multiple emails to be assigned to one account.

I agree.  My speculation is based on the e-mail being the clients and the paypal accounts main e-mail being the guardians.
