Thanks to the help from Leo_Valdez_25, I have a conversation between her and the thief.
It is clear here that the thief is making excuses. She says, "I have MAYBE posted my art online and she took it OBVIOUSLY." The use of these two different words in the same sentence talking about the same subject shows a sense of uncertainty and doubt.
Also, when questioned by Leo_Valdez_25 about where the art may be online, (whether it's on Instagram, Deviantart, or other), and the thief did not respond. This is a sign of her being unsure how to respond due to lack of knowledge on that particular subject, which shows that she was lying.
But, despite this, my friends, please do not say anything mean to the art thief. Let me and my few known associates handle this. We do not want to get in trouble for hating on the thief/ thieves and then have everything we worked for go to waste. So please please please please please please please refrain from the hate messages. Please.
And I want to say thank you to everyone who has been helping me with the evidence/info in this book to help -ArtemisPhoenix-. I don't know how Hannah feels, but I am certainly grateful for how much y'all are supporting it. Thank you!!!
