The $30 million toothbrush

As a drifter with virtually no material possessions,Jack Reacher's longest-running companion is his toothbrush.

With no time or room for long-term relationships, Reacher viewers can't generally expect any of his love interests to last more than a season.

However , this does not mean that some do not have an impact on the famously-stoic character .

Roscoe Conklin: The Best Love Interest So Far

Season 1 introduced Roscoe Conklin, Reacher's best love interest so far, with Willa Fitzgerald's performance reportedly nearly bringing author Lee Child to tears, knowing she would not be a recurring character.

Their dynamic made their eventual farewell heartbreaking but inevitable, with Roscoe pursuing a successful life in the town she loved, while Reacher's other romances have not been as interesting.

His romance with Karla Dixon practically ended with a handshake, and viewers found his lack of chemistry with Susan Duffy a low point in an otherwise phenmoenal third season.

Jodie: The Most Significant Romantic Relationship

The most significant romantic relationship that Reacher has in Lee Child's books is arguably the one he has with General Leon Garber's daughter, Jodie.

Jodie first appears in the novel, Tripwire, which is a fan favorite and often considered one of the best in the series.

While Jodie first met Reacher when she was 15, developing a teenage crush, the two meet again under unfortunate circumstances long after Jodie is grown and divorced.

What's Next for Reacher?

While it is not yet known which book Reacher will adapt for season 5, it is confirmed that unless the upcoming season 4 strays from the source material, his next love interest will not be the one.

Reacher season 4 is adapting Gone Tomorrow, in which he finds a companion in homicide detective Theresa Lee, renamed Tamara Green in the TV show, and played by Sydelle Noel.

Like most of Reacher's love interests, Tamara is a competent law enfocement agent, but as he moves on at the end of the book, their partnership ends with the story.

This is not always the case, as Reacher has considered remaining in one place before.

He already told Roscoe that if he was to settle down somewhere, it would be with her, but he comes closer to doing so with someone else.

In a blink and you'll miss it moment, the TV show has already set this relationship up.
