Floyd knows Amanda is mad. Her yelling over the comms earlier was enough evidence of that. Did Floyd care, however? No, not all all, not when it came to saving you, a small child, from the building they collapsed to take out thare targets. This was a Task Force X mission, so Amanda just wanted it done, not for the team to save anyone.
Floyd still didn't care after they returned to the safe house, watching at Harley coos over you as she begged to hold you, Floyd reluctantly gave in an hour into the walk back, your parents had been one of the targets, so obviously, you're now an orphan, he didn't know what to do now, yet, at least, so for now he sat beside Harley on the couch on the safe house as she coos and hugs you.
"Don't smother the kid, Harl's..."
Floyd says as Digger rolls his eyes at the sight from his chair, Floyd gives a look to shut up any snarky comment. Floyd looks back at you. He's dad, so he always feels protective of kids and knows Harley won't hurt you, so only trusts her to hold you.
