Thanks Fred! But it was a wild guess. Well, this isn't Ennis normal reaction so I guessed something else was going on. He got very nervous after Sevigny's visit. He had a bad premonition, which got me thinking too, but I ain't gonna say anything!
I was thinking as annoying as Sevigny can be, we probably need to thank him for asking the question that got Ennis riled.
In the earlier chapter, Ennis wanted to talk to Ellery about something, I hope he gets the opportunity to talk now.
