Normally when one is defeated (play with friends) your shown a message to say you've been defeated and then your sent to the menu. However it would be great if you could carry on watching the rest of the game instead. Otherwise trying to watch it on another person's device is an option sometimes but it can be awkward. You could show the defeated message then have two buttons one saying return to menu and one saying Watch the rest of the game or something of the sort.
