Definitely some discipline if she followed the twins into trouble (though she may have noticed he was harder on them most of all - for him, it was his way of trying to help them/keep them out of trouble and protect them like his mum wanted him to do). Oh, and Alicia now has a whole new empathy for what it's like to deal with a pair of twins! Percy's heart goes out for her for that ;) Interaction potential: since their children are so close in age, maybe they connected at one point to arrange playdates to socialize the children?
As for Malinda, she would definitely know Percy as the doting father regularly being pulled in by an over-eager child asking for sweets.
