"What was all that about, uh his father? Fitz never mentioned him before." "He was not a good man. Always telling Fitz he was stupid and worthless. I think that's why Fitz became so clever."

- Alphonso Mackenzie and Jemma Simmons

Friendship with Holden Radcliffe
"I can't do it. It's way beyond me." "That's your father talking. Isn't that what he used to say to you? Not enough, not smart enough?" "Why would you say that?" "Because I knew him. I wanted to tell you, but - I was afraid it would open old wounds."

- Leo Fitz and Holden Radcliffe LMD

While working studying in Glasgow, Alistair Fitz met Doctor Holden Radcliffe, whom he would often sit with on the train and show him pictures of his new born son, Leo Fitz. However, Alistair Fitz was cruel to his son, insulting his for not being smart enough and often calling him worthless. When Leo was ten, Alistair walked away and they never saw each other again.
