Steve stares at him a moment as if accusing Tony of something. "It's up to you two obviously." Which is to say he is going to throw his two cents in. "If I can make a friendly comment? Maybe point something out? I'd like not to be a hundred when I attend the wedding. It's actually a dream of mine."

His tone may be joking, but it's clear from the look in his eyes that he does legitimately fear being a hundred at this wedding. Please get married already.
