Samwell's reaction to Dany was probably the best part of the episode, though. I mostly didn't expect it, because Dany usually skirts around consequences.
Samwell is clearly upset even at his father being killed despite how much of a dick Randyll was, but it's horrible when he finds out his baby brother died too.
Samwell: idk could you maybe not murder my family and start keeping prisoners?
Dany: lol nah
