Ken hadn't thought of it that way, but until and unless he can reclaim his Digivice, that will remain an issue. The former offer is heard and appreciated, but it's the last that gets him musing.

"I'll fight!" Wormmon offers, but Ken-chan is looking contemplative.

"We could still get ambushed." And therefore Wormmon would not be able to respond in time, or be busy with another foe. Against Digimon there's little points in the human partners attempting to fight, but with a wider variety of potential enemies......"I know some judo."

Except that's not. Relevant. Is that relevant? He doesn't know. He quit it after he stopped caring about how good he was at things in relation to others, but the core of the art is self-defense...

"....Will that help?"
