I'm pretty sure none of our options allowed Jason Todd, or really anyone, to be our Robin. Him moving in with us is a ship that sailed when we accepted Talarast. In fact...
Spoiler
I'm pretty sure one or more of options get him dead, but I can't seem to find verification. Which is odd. I remember him getting killed. But I also remember that our current course of action doesn't get him killed, which I like.
