In Vikings, after Kwenthrith's brother dies, everyone pours out their wine. Were all of the drinks poisoned (or was everyone simply put off)? I find this unlikely, as when the scene opens, time seems to have already passed (i.e. they hadn't just congregated), and would everybody really have held their drinks in their hands for so long without taking a sip? Of course, we don't actually see anybody else take a sip.
Have I missed something?
Also- on the side- was that a bit of brother-sister romance going on, when Kewenthirth and her brother kept touching each other and declaring each other's love (and also judging by the look on Ecbert's and Ragnar's face).
