Controversial theory that I like because it circumvents the cliche 'Douchebag abusive father killed by his own kid':

Mercury and his dad had a half decent relationship. Yeah, it wasn't the best, but his dad didn't do anything that would make Mercury want to kill him. Mercury lost his legs not long before Cinder showed up due to enemies of his father attacking Marcus, and Mercury got caught in the crossfire. This means his legs are still healing from having to be replaced, which explain the bandages above his knees.

When the show catches up with the Blacks, Cinder and Emerald were watching the Black family fight against assailants (there for revenge, or fellow assassins wanting to take out the competition, who knows). They didn't interfere because Cinder wanted to know if Marcus was strong enough for her cause. They didn't see the fight from the beginning, they just came along to see the assailants run away, maybe get beaten up a bit, or maybe they were caught in the fire.

The fight mostly happens inside the house; Mercury and Marcus team up against the assailants. The attackers focus on Marcus since he is their target and Mercury is just a 'dumb kid'. The house catches fire, Mercury and his dad manage to either kill all the assailants or kill some and chase the others off. Marcus is mortally wounded in the fight.

Mercury pulls his dad out of their now burning house, and Marcus dies soon after. Mercury bandages his legs and stands up to walk away, then finally the conversation with Cinder happens.

Before anyone says anything about Cinder not mentioning other assailants; all she said was "your fight." This could mean a fight between Mercury and his dad, or it could be a plural 'your' as in 'the both of yours' fight. Mercury had time to bandage his legs before Cinder spoke to him; any assailants would have had time to run away to live and fight another day through the forest on the other side of the house. Or they could all be dead inside the house.

Marcus looks like he has been pulled away from the burning house, in my opinion, which is not something a kid who got fed up with his father and killed him wuld do. A kid in that scenario would leave his dad to burn inside the house.

The bandages are covering up reopened injuries from the prosthetics, which were reopened in the fight against the assailants.

TL;DR Mercury and Marcus didn't hate each other. Mercury lost his legs not long before Cinder found him, some wounds were reopened in a fight against his dads enemies which Cinder and Emerald caught the tail end of. Marcus was mortally wounded by one of the attackers and died while Mercury was pulling him out of the burning house. Any living attackers fled through the tree line on the other side of the house because they saw Cinder and Emerald; fresh people  who weren't attacking Mercury despite him bandaging his legs in front of them. Conversely, all attackers died inside the house. I prefer this theory.
