Theo's just bitten into an apple when he feels the summons, so he doesn't stop to put it down before accepting. He can get rid of it later if necessary.
Luckily, so he thinks, he gets to the summons before anyone else.
"We have explained Spira is the name of the whole world, and I just said Sir Auron is—"
"Okay, so if my question doesn't make sense because there is no precedent, could you as a native who understands more about the current context please make an educated guess about whether I, as a non-native, should in fact go visit him and say 'hi there I'm from another world and have a weird magic' or whatever."
"There's no should, the only reason we're gonna go see him is because of Tidus, he's not a maester or anything like that."
Eventually they arrive at the locker room where the Aurochs and Tidus are discussing strategy.
"Yo, Tidus, someone's seen Sir Auron in a cafe, wanna come?"
They leave the room—Lulu stays, but Kimahri and Kaede come with—and see a couple Al Bhed in the corridor.
"Hey! Al Bhed Psyches, right? Some Al Bhed saved me the other day, and... This girl Rikku gave me food and... Uh... You don't understand me, do you?"
The Al Bhed look at them in silence, so Kaede switches to another language and says: "He's saying he was rescued by someone named Rikku the other day."
That draws a reaction from them. "You speak Al Bhed?" asks one of them in the same tongue.
"So you can translate," he tells Theo in Al Bhed, then looks at the other Al Bhed. "My mother was Al Bhed. I'm Cid's nephew."
"Cid's nephew is a summoner?" one wonders.
"Wait, I thought his sister was dead..." the other says.
"...yeah, she is."
"...Rikku is Cid's daughter..." one of the Al Bhed ventures.
"Of cooourse she is," Kaede sighs, then explains that "This pilgrimage is absolutely riddled with coincidences. Anyway, I gotta go now, nice chatting with you, if you're still in town after this game hit me up, we can hang out together." He winks, to no visible reaction from the masked Al Bhed, and continues making his way out.
Tidus blushes when Theo gets to the wink part but asks, "So Rikku's your cousin?"
"Apparently. And by the way, try to avoid mentioning that I'm half Al Bhed to Wakka."
