Nico was untrustworthy.
What was a person who couldn't keep a promise worth? Nothing, that's what. And now it showed.
How many times had he let down his friends? Five times? Six? He had already lost count.
Not that it mattered, anyway. It was several times too many.
Now, they were at war again, and he was stuck here. Nobody would rescue him, though. They were too busy, and heck, wouldn't it just be easier to leave him here? Where he couldn't betray someone?
Now, with just his thoughts as companions, he realized something.
He was untrustworthy.
He was worthless.
