Also known by and referred to as ‘G’, Callen’s character has previously had a lot of questions regarding his past and it wasn’t until season 7 that Callen learnt his original birth name – Grisha Aleksandrovich Nikolaev.

However, the series 13 premiere unlocks further pieces of his background, including mysterious family members.

New NCIS reveals his back story

Series 13 of NCIS: LA contains links to previous flashbacks in which Callen is forced to recall he once had an older sister.

The first episode of the new NCIS season shows Callen finding operations manager Hetty burning files regarding foster children who were put through profiling experiments and had cognitive tests ran on them.

Callen suspects Hetty is keeping secrets about his past and later discovers his own file, Subject 17, realising he could have been one of the children experimented on.

Episode 1 ends as he is reading his file over a flashback of his younger self watching something on a projector.

What happened to his sister?

In the previous series’ flashbacks, Callen realises his older sister drowned in a river.

His sister was then buried under the name Hannah Lawson, although the actual Hannah lived with the assumed name of her dead foster friend, Amy Callen.

Amy Callen’s character was portrayed by Lily O’Donnell, actor Chris O’Donnell’s real-life daughter, while her brother Charlie O’Donnell portrayed a younger version of their father’s character in flashbacks.

Lily O’Donnell, born Lily Anne O’Donnell, is an American actress now aged 22.

On Instagram, @chrisodonnell has uploaded content featuring his daughter, including birthday posts.
