The rats are dead, but then we see something worse. Goblins. Thousands of them.
"RUN, I'll hold them off!", I say.
"Ren, no." says Sir.
"Just go!"
"If you die in Oblivion, you die in real life."
"Then go, there's no reason we should both die."
"We can outrun them, there's an exit right here."
I follow Sir a little further down the tunnel until we find a ladder. The goblins are right below us, screaming. When Sir opens the hatch that leads to the outside of the sewer, I grab him and say
"Sir?"
"What now?"
"You should have left me behind."
Sir looks horrified at me, realization showing across his face. He tries to struggle, but I throw him down, leaving his fate on the hands of the goblin horde. Then I climb up, get out of the sewer and close the hatch.
