Kato laughed a bit, looking at Trommel. "May we have a moment to discuss it?" Once the Guado servant walked off, the blind Guardian returned his attention Sera. "You have no need to worry about us. Why do you think I've been taking the time to train Soren? He's strong enough as is to defend you until you reach Zanarkand. He's strong enough to give Seymour problems. I'm almost betting on the fact that Seymour will challenge us. Soren will kick his ass, regardless of if I'm involved in the fight or not. And, believe me, I will be if he threatens Soren. I don't think he can beat the kid, let alone both of us." He smiled reassuringly, taking Sera's hand and squeezing it lightly. "We'll be fine."
Renok cleared his throat. "Maester Seymour can't harm any of you. He can't harm or impede a Summoner's progress. Attacking her Guardians impedes her progress, correct?" he asked, looking from Kato to Sera.
"Ah, right...this is Renok," Kato said with a smile, gesturing to the Al-bhed. He didn't realize it, but he was still holding Sera's hand in reassurance with the whole thing. "Our past fights have been misunderstandings. He joined Mushroom Rocks Bay to show the Maesters that the Machina weren't evil and that they could help against Sin rather than being subjugated for causing Sin to come. We had a little talk and...well, he'd like to be your Guardian as well. To show that the Al-bhed aren't all bad."
