Tyler was nervous and tense the whole time. They've done this before, Bonnie had been able to pull him through, but they were in a different world and who knew if that affected the way this worked?
He kept his eyes on Gabby the whole time, reassured by the fact that she was watching Bonnie for any hints of pain. When Bonnie puled him through finally, the biggest weight was lifted off his shoulders and he felt like he could breathe again, in all senses of the world.
He hugged Bonnie first, after she got done poking him, and only let her go from his bear hug so he could find Gabby and just kiss her and hug her and spin her around. The nerves and anxiousness from before was completely gone and he was laughing and smiling and just more like his normal self.
He went around hugging pretty much everyone there, just relieved that he could do again. And he insisted on them all going out to lunch because what better way to spend time following a resurrection?
