Blizzards remind Shark of a certain sister back at home. He missed her, sure, but Gotsumon was a near perfect substitute for Rio and such, it lessens the pain a little. (By virtue of replacing it with a reminder of what an annoyance a bossy sister can be.) As such, he would have been content with staying indoors and enjoy himself by keeping warm.

Or he would be if it weren't for the ungodly screeches he's hearing. He briefly considers ignoring it, but that notion is tossed straight out the window almost immediately, so Shark takes it upon himself to make the trek outside, Gotsumon in tow. There, he finds Impmon.

"Oi, if you're going to have a screaming match, take it elsewhere."
