In a follow-up post featuring photos of the actor from throughout the years, Lenkov wrote, "T, as I told you many times, I fell in love with you at the first audition. You came in with a towel on your head mopping up sweat, and I was smitten. You charmed me into making you a regular… on the show… and in my life. You were family. And I will miss you every day, brother."

He added, "PS: when we spoke last week, we laughed at how right you were from Day 1. Five-0 was our dream job. And I was so lucky we got to share that magic together."
