Jason is rambling on in order to show Speedy he understands her methods, her way of thinking, her tactics. That's why the weapons go from long range to short range to very intimate (the twisted blades). Whatever "distancing" Speedy does to move beyond her past, Jason is bringing it in her face, trying to turn her to his cause.
Jason knows he will need an ally, sooner or later, that he can trust. Not necessarily his own Robin, but an Arrow to his Bat, should he need to face off against other heroes. Strength in numbers.
