Hero of Ages Update (no spoilers of future events or other cosmere please)

I am at the part where Telden got Vin to drink the spiked wine.

I am really impressed by Yomen as an antagonist. I don't think he is an allomancer. My guess is that he is able to use atium because of a Hemarulgy spike.

Spook has really grown as a character and turning into a leader. His plan to flood the canal is interesting. They have just taken Beldre hostage. I am suspicious there is more to her than meets the eye.
