Pretty cool (pun intended).
After materializing longboards for some radio wave surfing, Subaru's contacted by Orihime to search for an Oopart in the mountains. Subaru's a dumbass heading to the snow without bringing winter clothes, but Raana bails him out. Cancer wears a cute little white suit when he walks in on Misora deciding to join in on the hunt. Yeti Blizzard attacks, and he and Rockman have a cool little battle before he retreats. (I love how Subaru says his name, "Burizaado"

) And we finally get to see Yeti unfused from his human partner, neat-o.
Next ep: Harp Note in action, and the return of Thunder Berserk!
Unfortunately, I was going to post a link, but YouTube seems to have taken it down already. Rats.
