Danny was torn on what to do. On the one hand he wanted to rush out there and help but on the other hand he knew that he was too important for the wellbeing off an entire world to rush into a fight that was too much for his Digimon to handle. The fact that Angemon left before he could ask what to indicated that this might be such a situation. Salamon in the meantime tried to sneak out of the room in order to see Angemon fight hoping Beelzemon wouldn't notice. Hawkmon at least did notice but didn't say or do anything being too busy with coming up with advice for Danny.
