Since everyone already got past Mettaton, that means that the elevator in the core's lobby is not in use, so Silver uses it to get to the top, and immediately gets attacked by mercenaries(Knight Knight and Madjick). Both his eyes turn red and he crushes both of them with the air.
With the last bit of air in it's lungs, Knight Knight attacked with her Good Morningstar, and I rolled a 6, so it hit Silver.
They then both died.
"Ow...That was a little difficult."
(Last time I killed something in the core, it gave me enough exp to go to LV 6, so I'll give that to Silver)
Silver's LOVE increased to 6.
He proceeds into Mettaton's room.
