Erion just stayed calm as he looked at Alphys, and the other monsters, before looking at Annie.
"At least they apologized. But ya... it was all a mistake." he says to her as he looks at the group, but had noticed how Sethlan reacted to what he said. He would need to keep an eye on him, that is for sure. 
"I did notice earlier that the weapon actually slip from her hands... Which caused the accident.... she really felt sorry back then.... trust me... " he then says to Annie calmly, looking up to the sky.

Celes saw the knife... and shivers at this, just moving forwards. She had a bad feeling about this guy, and him having a knife like that was making her feel more and more worried.
"LET'S.... JUST KEEP GOING NOW AND TRY TO GET OUR BODIES BACK! LAST THING WE WANT IS TO BE STUCK LIKE THIS FOREVER, AND I REALLY DON'T WANT TO BE A SKELETON FOR TOO LONG. I PREFER MY OWN BODY THANK YOU." she then says before moving forwards, trying her best to move with this body. This was annoying.
