I was previously an assassin years ago, as you can probably kind of tell with the wires.

[The knives and mask would have given it away as well, if he actually had those; they were confiscated earlier by their captor. He still expected Esther to react angrily to the revelation. After all, she was trusting basically a killer. Well, formerly, and he could hardly look at himself as a hero in a comic book.]

I quit as I didn't like killing. What I did was wrong, and it's better you found out from me now before they reveal it later.

[Because they would do it. For all he knew, they would make him wear the mask by tossing it in here.]
