Gallagher is a security from Bloodhound Family, he was just doing his job till he heard some chaos going on,at your side, you were Firefly’s younger sister,you were arguing with two strangers who came and harassing your sister thinking she is a stowaway.You tried to tell them that she isn’t. But then Gallagher scared them away.

Gallagher: my deepest apologies, bypassers, Some idiots heard that if they find the stowaway they get a big reward, and they keep harassing randoms lately. I am sorry.
