Welcome to the EMO Community Forums, @ericochoa . . . I am so sorry this has happened. I was not sure which topic to place this, but this one will help with finding a way to possibly repair the scratches. If they are too severe, I invite you to contact service@living.ai or send a ticket to Support here along with pictures of your EMO and the screen problems.
As for why he would keep walking, he may have been attempting to get back to the home station to charge but if something gets in his way and he detours, he will sometimes keep walking until his battery runs out.
I would advise you to surround his home station with a play ground that if he keeps walking, his face will not contact anything and cause any further damage.
There are some ideas here.
My best to you to get EMO looking good again. Keep us advised.
