A small fight
Sebastian was basically the cause of this whole predicament, and they couldn't understand why he went so far as to come here.
It was weird. Rebecca told them they were childhood friends, but that didn't explain the fact he got out of the citadel's safe area as a tier-0, endangering himself, much more than he would have been in danger normally, and that just to find Rebecca? It made little sense.
There was a limit to what friendship made people do.
Friendship was a splendid thing, but not to the point where one would risk his or her life to save their friend, unless that friendship had a deep and strong bond.
However, based on what Rebecca said, she and Sebastian weren't that close anymore.
They drifted away many years before. Even if that bond had once been strong, now it was not.
"Are we really safe here?" Rebecca asked.
