According to |this video around the 30 minute mark, they talk about an episode where Lincoln invites friends over in order to get special treatment from his sisters, so the sisters do that with their friends, and Lincoln invites two friends and so on.

This I think is the plot of "Friendzy" and I think where Sam will make a reappearance.
