Well, being in a long coma won't help his issues, obviously. And it won't help you get him out there to fix those issues. Unless you mean to put him on hiatus while you ponder it over?

Perhaps this draft might open up some opportunities? I can imagine Leonhardt and Saleh having a discussion about protecting those they care about, and what it's like to lose them, etc. It could happen either after putting down Kain, or in the draft aftermath. Again, it's just a thought. I'm seeing a great opportunity for CR here, whether Leonhardt gets infected or not.
