Sure, the fact that Sam still leaps into Jack’s arms when he is scared is a bit creepy. And, yes, the fact that Jack randomly calls out ‘Saaaaaaaaaaaaaammmmm!’ when he misses him is… well… odd for a man who is about to be married… to Sam’s sister. But we think both young men can put these strangenesses to rest for the Big Day and focus on Mac’s happiness. (No, no we don’t. But we had to say that here so Mac would not be worried).
