Gnah, this is one of the pages that work way better on paper - I was very disappointed, when I scanned it and really have to consider redoing the bottom panels. the hatching does not work.
I did not want to waste panels on explaining how von Stein knows, that G is running around: On the previous page and in this one (top right) there is a camera. The whole villa is trapped. He is quite paranoid about burglars- terrible, if they could get away before he could use some experimental drugs on them.
