In the time he had grown used to Mantis as well as the other Guardians, Loki had also developed a quietly protective instinct over her. Occasionally her perceived naivety grated on him, but he also knew what it was like to be treated as though you were incapable of protecting yourself. He had spent a lifetime proving that people shouldn't mess with him just because he wasn't as muscular as his brother. This aside, Loki curbed his tongue from any protest. The others were too tired to put up much of a debate.

His selfish, less pleasant side didn't trust anyone but himself to do it.
