Vash listened closely to the Viewer’s explanation, but much of what he said seemed to raise more questions than it answered - particularly the fact that the Viewer himself didn’t bring them there and the concept of a “snap-back effect” caught him off guard a bit. Regardless, he allowed the Viewer to continue without interrupting. 

As for his question about the wishes, it was clear that the saying “be careful what you wish for” rang very true here. He supposed he should’ve expected as much. In that case, he’d have to think carefully about what wish to ask for, considering the potential side-effects and drawbacks to each wish in order to decide what would be best for Gunsmoke. Additionally, he’d probably have to be very careful in his wording for each wish, too. 

In the end, while he still didn’t know much about what to expect from each trial, he saw that there wasn’t much point in backing down, as there was a whole lot to gain and not much to lose. Though, he did worry that one of the trials may require him to take the life of another - and if that were the case, he’d forfeit once he got that far. But, in the meantime, he decided he might as well go for it. “I also accept.” he spoke, stepping forward. “If I have any opportunity to make my home planet a better place then so be it.”
