I've always knew lucas was one scary guy since in his introduction he was throwing 'casual' threats left and right and is fulling able to go through with it, but him interacting with athy so far has lessened my guard. Now that I look at the last two chapters, espescial this last panel, I get the chills.
We're lucky lucas got attached to athy, because of this I think this kingdom got a 'get out of jail' free card...
