Haytham has just found out about his lost son, Connor, and feels obliged to Ziio to look after him after her death.

Haytham decided to try and bond with Connor by taking him paintballing where he can invite one friend, Haytham doesnt no what he is getting into as Connor chose Altair to be his partner against his Father and Charles Lee (up to anons choice really)

Haytham thought it would be a bit of fun but doesnt realize Altair plays to 'kill'.

Bounus if someone like Shaun, Malik or Desmond say "you're going to unleash Altair on your father.......paintballing.........you must hate the bastard"
