Why else (Patreon)

Sasha guesses what her reason for wanting to go here, while that could be part of it as well, but not fully.

Sophia herself doesn't hate it, but also isn't exactly the biggest fan of it as well, but it's not really about the sword.

This is during the morning when Jonathan goes to Sasha to see her during their surprise visit. There was still time, so they decided to go to the tourist landmark first.

I'm sure you're well aware of what happens next.
