Thank you so much! Reading over the script I DIFFIDENTLY didn't make it clear, up until the point were Karkat goes to hide, he'll be the only one on stage. Him and Gamzee are talking through something similar to 'MSN' or Skype. That's why he had no idea were Karkat was. On stage, we plan on having a laptop set up and haveing those 'MSN' like bings just before Gamzee says anything
I hope that clears that up? I'll go add a little bit explaining that in the original post. I can't believe I forgot those stage directions!
