Bruce Wayne and Altaïr Ibn La'ahad meeting when Bruce's lost in the timestream and falling so hard for each other so fast. They're both obsessive perfectionists sacrificing themselves for their mission.
When the JL finds Batman using Red Robin's data, he pulls Altaïr forward in time with him.
The Batfam don't know if they approve (bc of how happy Bruce is) or concerned (bc they enable each other's insanity and Oh God There's Two Of Them).
Either way they get a bamf stepdad out of it who is not above using his skills to mother hen them.
