   Summary

   You happen to notice that Gregor seems to take a couple days off and nobody else seems to be worried. Turns out according to Faust he has a habit of taking some time off each month and wishes to not be disturbed. Being the kind friend you are to the man, you decide to give your services to help...only to realize this is a side of Gregor you aren't used too!

   Gregor ends up going through a heat as a side effect of his bug genes!
