The two are very close ever since the kickstarting of the series' plot and even though they get falling-outs, the fallouts mostly come from Zachary's autistic focus on things. She even helps with the Myles Bots though she puts them in protective custody in a misguided attempt to protect them.

Lex Belebome
Despite Zachary getting rebuffed at each attempt, Lex only does so out of lack of social skills. They have been correctly predicted to have an episode focusing on their relationship and it's currently predicted whether the writers would choose Xara or Lex as Zachary's secret keeper. They finally become friends in "New Friend" prior to Zachary's invitation to the Myles Bots.
