Proof that I haven't read the OP in full probably here but i just realised the actress who played Nikki Jardine on NCIS is on This Is Us
I have an episode of NCIS on that i am half paying attention to & Jardine came on & I knew that I knew her voice & that she was from TIU. I knew it had to be her, although would've been funny if I was wrong
I am surprised I haven't noticed it before given TIU is in S5 now
