DL...
Danny Messer and Lindsay Monroe. Need I say more?
Well, I guess so if you know absolutely nothing about them. ><"
They're both characters from CSI: NY, played by the wonderful Carmine Giovinazzo and the charming Anna Belknap.
In the first episode where Lindsay appears (to replace Aiden Burn who was fired for planting evidence) Danny starts teasing her. Giving her the nickname Montana, which clearly irritates her at first, he probably made work hell for her. She stuck through it, and slowly Danny learned to accept Lindsay. The nickname Montana is still used, but not to annoy her, and in almost every episode there is a little time just for some DL interaction. The two get along wonderfully, and there is teasing/banter back and forth.
There is a definite chemistry between the two, but if anything will happen is unknown. The CSI shows don't seem to encourage work relationships, but hopefully they will make an exception for this pair. I've shipped them since the first episode I saw them together (Zoo York) and I've slowly watched their relationship grow to something more than just co-workers. If they can't become a couple, then I'd just like to watch them grow into the best of friends.
