"The special force... those fckers causing trouble again..." Mera sighed while gulping down some whisky, "But if branding them saved your butt, then I think it's fine. However, next time I'd like to be informed about things like this."
Ashton had just finished narrating a false tale yet again. His improved intelligence definitely seemed to be doing wonders for him. This time it was a tale about how the special force was looking for suspicious people who could have relations with the resistance.
Since Ashton was a mutt, he was their prime suspect. The suspicion on him was also reinforced by the fact that he was present in the same group as Lucas who was killed during the test. Thus he had to shake them off his tail so he branded Duncan and Daniella as his slaves.
Obviously, Mera did not have any reason not to believe him so she let the matter go for now. But she made it clear he knew this was the first and the last time she would let something like that fly.
