* Playful teasing: They often tease each other playfully, showcasing a comfortable and friendly dynamic.
* Shared interests: They often participate in activities together, showing a common ground and enjoyment of each other's company.
* Isabella's clear crush: Isabella's feelings for Phineas are often hinted at, but Phineas generally seems oblivious.
