If Cutie and his mom are only going to be together for a couple of days you may want to keep them separated to minimize stress. If this isn't possible you should make sure Cutie's mom has a separate food, water and litter area and plenty of places to hide if she wants (cats especially like to escape to higher elevation so you may want to put her bed or food up high). If he continues to try to make friends you should separate them if she's hissing to prevent them from injuring each other. It's not uncommon for cats to act aggressive when they're fearful or stressed, and this change in environment is likely stressful for her. Good luck!
