"Surprise!"
Tim had been cold and distant for over a week.
"I don't know what I did," Tony griped at Abby, draping his body over her empty desk chair like an abandoned garment. "Give me a clue."
"I don't know, Tony baby."
He went home - alone - and nearly suffered a heart attack when he opened the door to a loud "SURPRISE!"
Tim sprang forward and grabbed him. "Happy birthday!"
Tony was lost.
Even Gibbs was there; he glowered by the punchbowl and said, "It's your party, bonehead."
Afterwards, Tim apologized for his silence. "You know secrets aren't my thing."
