Oh Oh! Here's a completely unfun slightly unnecessary tidbit that I've been hiding!

One of the "last straws" that drove Thierry to having romantic feelings for Nick was when he heard what Nick's last situationship said to him.

Long dramatic argument turned lecture short, Nick's ex girlfriend told him that she'd started taking "the pill" after having an abortion. Not because she didn't feel she wasn't ready for kids or because she didn't want kids. Because she had talked plenty with Nick about wanting kids. But, she's a massive bitch and told him she was only sleeping with Nick to make another guy jealous and that she didn't believe Nick deserved to have kids and most certainly not -her- kids.

So, instead of checking himself out (the man has a gun stash that could make John Wick cry and Lara Croft jealous) or into the ER, Nick turned to the only person he felt he could trust at the time... Thierry. He trusted Thierry because he'd gone through a divorce himself among other reasons.

Oh... and where did this argument occur? A wreck room for agents at the Louvre... they weren't alone.
