Mediator

Mediator pattern has behavioral purpose and applies on objects. The pattern defines an object that encapsulates how a set of objects interact. It promotes loose coupling by keeping objects from referring to each other explicitly, and it lets you vary their interaction independently.

When to use

a set of objects communicate in well-defined but complex ways
reusing an object is difficult because it refers to and communicates with many other objects
a behavior that's distributed between several classes should be customizable without a lot of subclassing
