Well, then we get into what defines 'interrupted'. The percentage rule could work - characters introduced in the last 10% of the story perhaps? In a 45 minute episode, I can't imagine a scenario where characters pertinent to the plot of that episode are being introduced post-40 minutes in. Always possible, though.
