Chen grimaced internally as they rocketed down the hole. He wasn't expecting such a fast descent and was unprepared for the sudden stop at the bottom. He took a minute to reorient himself and breathed in and out deeply. "That was fun!" [i][color=Red]'Your death will be very painful.'[/color][/i] Chen followed Mettaton and stopped at this unusual scene that was laid out before him. 

"Why is everyone so tense?" He asked innocently, meanwhile he subtly shifted into a fighting stance as well. His posture was turned sideways in regards to the enemy, leaving less room to hit him. His heels were slightly off the ground, making sure that he could push off in any direction as quickly as possible. He had crouched slightly so he could grab his dagger faster. But his face suggested complete ignorance and naivety.

[i]'This is pathetic. If everyone attacks at once than this monster would be destroyed easily. Why would they try to talk to it when it's clearly hostile? It's stupidity at its finest.'[/i] Chen wanted to shake his head in disappointment, but that could tip them off. He needed them to believe he was on their side. At least until he could get to Frisk.
