I meant the start of this half season may have been a good spot. Apparently they originally planned to air this episode at a different point but then they swapped around the order a bit. I forget exactly where it was meant to air, possibly right before the attack on Hilltop. I think that just goes to show you how even the writers didn't know where best to place it.
And thanks to this comment, I googled a bit to see if they've started on the Rick movies. It doesn't sound like that has moved much at all yet, so it should be well down the road still. Part of me wants to say the main series ends before we ever see those, but I get the feeling that they'll want to reunite him with his kids at the very end of the show.
