Females are dominant in the hierarchy; it's likely she's maturing and realizing that she must claim dominance over him. After being separated, the feeling probably intensified even more that she must make him realize she's dominant. Leave them alone. They'll sort it out. That's how cats establish dominance, and as long as they're not drawing blood badly, they'll sort it out. Blue will either relent to her dominance, or go hungry. When Blue shows her respect by submitting to her dominance, she'll leave him alone to eat. But try not to get involved, they'll sort it out soon enough. You'll only make it worse by interfering.
