"But we know people who can use that stuff here, I've got this friend Rikku and she can blow up anything..." But it wasn't the time to talk about stuff like What If and Might Have Been 'cause they didn't have anyone there like that.

Since the entrance wasn't that big and Tifa beat him to it (and Tidus knew very well not to try and insist he do it instead of her), he stayed more off to the side, tossing aside other rocks and broken branches that were going to get in their way. Once Tifa was through, he was able to climb up and take her place, sticking his head into the hole to test it out.

"We're gonna have to make it bigger, hang on for a sec-" At least it was a problem easily solved, as Tidus just started shoving rocks behind him to fall down the debris slope. Within a couple of minutes it was big enough for him, as the smaller guy, to wriggle through, though Light would probably have some issues with it.
