Had to re-watch before I could be sure. I think they retconned Gibbs' age again. According to last night's headstone, he's now 63 or 64. Have to check the other episodes, but I think he was younger on the earlier headstones.

Just so not feeling a Gibbs/Jack romantic relationship. I think Jack's on-screen chemistry is better with Vance. It might be interesting to see Gibbs navigating a friendly working relationship with his boss's SO...
