Oh, I know that, and I always side-eye him for that, because every time that Genie has returned, he, or rather Luke just lights up! There was the fake wedding to celebrate Luke & Laua's 25th Anniversary for the viewers, where Laura woke up, but then it was retconned it was only temporary; and then when Laura came back, engaged to Scotty, around the time that Lulu was recast, I think. That moment, when Luke is sitting down, hears footsteps, sees that it's Laura? I could literally see Geary light the fuck up and then Genie's smile. Despite his bitterness, those two still have IT.
And I understand, trust me, I do, why he wouldn't risk doing it. Wish they could have zoomed or Skyped both Luke and Lucky.
