Zack does hesitate for a moment, no he isn't sure. He used to be so sure in his choices, in himself and his dreams but what's the point of them when you've already died and failed? So no, he isn't certain he wants to be alone right now but he can't possibly ask Geddoe to come with him all the way. He already embarrassed himself and he doesn't want to anymore.

"Yeah...I'll be fine. Thanks for walking me this far. Who knows maybe our paths will cross again sometime." He smiles almost bittersweetly but doggo is already heading off and so he starts to as well. "Be safe Geddoe! I hope to see you soon!"
