Fitzsimmons (or fitz-simmons) is the ship name for Agent Leopold Fitz (portrayed by Iain De Caestecker) and Agent Jemma Simmons (portrayed by Elizabeth Henstridge) from the popular action/drama series Marvel's Agents of S.H.I.E.L.D. The name is commonly used in the context of the show, because Agent Fitz and Agent Simmons spend all their time together.

Skye: Yes! I love it! I ship it!
Antoine: I don't.

A name that belongs to only the most beautiful girl. She'll make you smile and never ceases to look amazing. Shes hard to reason with when she has her mind set on something, and sometimes very stubborn. There is no end to her beauty or smarts, One would be nothing less then blessed to be with her.

She's also good at Zelda.

Very charming, handsome, and gentleman-like. The most loving and kind man you could ever meet. Very difficult to not fall in love with one.
I met the man of my dreams tonight, and i think this one is definitely in the category of fitzsimmons.
