Barbara from Skarsgardfans has some ideas about these 2 pics, but she won't spill, lol, not yet anyway.
She also has screencaps from most of the previews so you can get a closer look on the action and see things you wouldn't notice just from viewing.
I’ve seen some other spoilers that pretty much confirm my suspicions of what leads up to this but I’m not spilling until closer to when that episode airs. (note the red “stuff” on Eric’s shirt) Yup. Bill Compton may be getting a bit of viking medicine here!
