John just enjoys the view as he lets his hands slide out of Gladio's hair and rest on the Sentinel's broad shoulders. Not as bad as he thought means Gladio probably thought he was something ancient. The gray hair and worn body probably lend themselves to that impression... and calling the man things like 'lad' and 'young buck.' It's a relief to know his Sentinel is more or less within the acceptable range of ages. The very, very low end, but still feasible for someone like him not to look like a completely desperate old lech around.

"But which is mightier?" he asks with a smirk before curling down and taking advantage of Gladio's upturned face to kiss him. He tastes, not unexpectedly, like soap, but that's fine. Everything is just fine for now. John pulls back and stands up again before speaking. "I think I like my chances with one over the other, at least. And I suppose I'll just have to pull the older and wiser card if it comes up."
