There are some episodes that explore their relationship in a playful way, such as:
* "iSaw Him First": Freddie develops feelings for Sam, but she isn't interested in him romantically.
* "iGet Pranked": Sam tries to play a prank on Freddie, but it backfires and ends up with them getting closer.
* "iGet a Job": Sam takes a job at a restaurant and Freddie comes along to support her.
* "iDate a Bad Boy": Sam dates a boy that Freddie disapproves of, leading to some tension between them.
While there is a lot of playful flirtation and banter between Sam and Freddie, they remain firmly in the "best friend" zone throughout the series.
