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.
And eventually Tidus thinks they'd best go check on Kaede and the guardians.
Sure! By this point, Theo has probably cleaned up a rather large amount of the surrounding area and is quite pleased with himself.
He'll fly them back up to the temple if Tidus is willing to be carried again.
And five minutes after they get there, Kaede walks out of the Cloister, somewhat faint, supported by Kimahri.
"Nope," he says. "But apparently it doesn't seem to work here – standard circles didn't summon anything."
"Yeah, we tried just a bit ago out in the forest – the circles are, uh, basically circular with writing and some other things around them? I can show you one if you want, but probably shouldn't do it here because of the temple."
"Can't you just change parts of the floor into a small one and then change it back?"
"– I mean, I could but I'm not sure they would take too kindly to me even temporarily defacing the floor?"
Out they go—Kaede recovers some on the way and can support her own weight.
"Okay, now let's see it."
So he does a circle in the ground, making some of the grass into dirt in the pattern of a circle designed to summon his friend. "Usually requires a mortal to complete it, so this one definitely won't work."
She looks. "Yeah that looks nothing like my kind. Gimme space, I wanna summon Ifrit."
She doesn't answer, but starts dancing, and moving her arms in front of her body. A ball of flame appears there and falls into the ground, spreading into a circle of burnt and dead ground under her feet. A magic symbol flashes on the burnt ground, and it suddenly shoots up into the sky, with Kaede on top of it, pushed up by a transparent sphere containing a slumbering fire dog thing. It wakes and stretches, causing the sphere to explode and the rock where Kaede'd been standing to shatter. She lands on the dog's arm, and they both fall with a crash on the (mysteriously not damaged and lacking any holes) ground.
It's all very flashy.
"This is Ifrit," she says, patting the dog's mane.
