Haha yeah, the interaction of Floki and Ivar in general was lolsy, facial expressions so trollish.
This episode was Ubbe's for me, finally growing into the notorious intense character he was, most books I read around these characters (2 different book series), Ubbe was allways THE guy, physically imposing unbeatable warrior, not the smartest tactical strategist like Ivar (latter Ivar, current one is just emotional psycho), but incredibly superstitious as fuck true viking (to insane levels btw) and natural leader. In this episode we kinda saw him interact with others besides his petulant brothers, growing from a teen to a man, and showing he is truly is closest one to Ragnar in pure fierce attitude, besides Björn.
