If you think about it for a second, it's actually both. I'll be vague on a couple details that you haven't gotten to yet in CS3 Spoiler: CS2 Emma knows that Vita is doing something with the Divine Knights. Emma also has a fairly solid grasp on where the seven Knights are and knows which ones are easy to awaken and which aren't. Four of the seven are effectively out of reach during the events of CS1 (Testa-Rossa requires an Arnor, one of the remaining three is known to be MIA, another is very difficult to locate and the last is... not one Vita wants) which leaves Valimar, Ordine and Zector. The latter of these is technically available so far as Emma knows (in truth it actually isn't by that point) but it's not located anywhere convenient so it's out regardless. Vita needs at least two Knights for what she's doing. That means that for Emma to find Vita, all she really needs to do is plant herself in either Ordis or Trista, confirm whether the local Knight is still there and then wait for Vita to come to her. Trista makes more sense because Thors is right there and it does offer the opportunity for travel if it becomes necessary. Yes, it's the same character in all three cases. You really shouldn't read anything into it though, it's an extremely generic one. For some details: Spoiler The 'Thousand' thing with Kevin's new title is explicitly taken from Rufina's title. That they're the same is thus not especially eyebrow-raising. That the Fourth Anguis' title also uses it is pretty sure to be a coincidence. Like I said, the character (千) is entirely generic, it's literally just the way that 'Thousand' is written; it's also used in Testa-Rossa's nickname 'Demon with a Thousand Weapons' (千の武器を持つ魔人). The Fourth's background as sketched out in CS3 doesn't really provide any reason to imagine a link between him and Rufina. Now, for the longest time I was very convinced that there was a link between that Anguis title and someone else we know about, but that was before Falcom revealed that the bit in Sept Archive where they identified a part of the title (which we'd already heard in Ao) as belonging to the Fifth Anguis was a typo.
