When they meet, there are cultural clashes and misunderstandings. For example, his dad doesn't understand modern technology and his mom is shocked by the magical creatures his dad brings along. Another idea is that Percy has been hiding his true self from his parents, and when they finally meet, he has to come clean about his adventures and powers. This could lead to a range of emotions from disbelief to pride. Or perhaps there's some sort of danger that forces Percy and his parents to meet and work together, and in the process, they really get to know each other for the first time.

But as they are forced to spend time together due to some threat to Percy, they start to see the value in each other's approaches and slowly build a relationship.
