"Oh." When presented with this new information, Wormmon retreats down onto Ken's shoulder, where he flops like a rather leggy scarf (in a hoodie).

Ken immediately has a good feeling about this person, because she was considerate of Wormmon. "You take good care of her, then."

He has started to wonder, given that the train has been a nonstop junk food binge for Wormmon, whether he should be looking more out for his partner's health. But it's also....very hard....to refuse anything that makes Wormmon happy.

Ken's life is so hard.
