That is a good reason to have the Marrok come, but it was not him who knew about the hybrids. You will have to wait to see who tipped him off! -plot twist begin blooming in mind- hehe

I do not think Avina would want to tell them. Brian has been so against her relationship since the start that he would do anything to stop her from going deeper. Including the idea that Avina would not need the added worry of the pack distracting her from doing what she would have to do. 

Yay! I'm done for a while too, until I have to do dinner anyway xD
