This was the best episode so far since episode 4. With the past stories and new allies, it turned "the basement" episode of Vinland Saga.
The only problem is:
Why Thorkell didn't talked or think about the sword reflection? He can't be that dumb...Or can he?!
I'm really seeing muscle fibers instead of neurons in Thorkell's head.
...This anime needs S2 after Attack on Titan's final season. It looks so damn underrated on MAL, so it needs some sharing.
