Oh. Ohhhhhhhhhh. This happened because this person was protecting their partner! Wormmon instantly feels way better, and turns around. In fact, now he looks a little awed.

A partner who protects their Digimon....that's so tough. It would be nice to be protected by Ken-chan -

But no! That is WORMMON'S job!

"You're a good partner," Ken informs Nara'a, while Wormmon gazes up in silent admiration. "But, what was that...?"

Something from this person's world, perhaps?
