"Hmmmm..." She seems to be doing math. "...Lots."

He hmmms. "I do have to get to the capitol at some point. How many do you want me to answer before you'll let me cross your bridge?" He thinks three is the traditional amount, but they hadn't set any terms or anything, maybe she wants to do more. 

"I think one more, unless you want to do more than that. And then maybe I can come with you!"

"You should! I guess I'm better at riddles than I thought, but I still want to hear more of them, this is fun!" And that way she won't be stuck here being bored anymore.

"So long as you don't mind, Alyssum?" He adds, looking around for him - he hadn't really been paying attention and kind of lost track.

"Sure, whatever."

"He's been like this about everything so far," he tells the Sphinx, "-is 'the Sphinx' your name?"

"Yes! Kind of? It's my title, really...? But I don't have a name like geese do."

"...Do you want a name?" 

"Maybe! They seem interesting."

"Okay... What kind of name would you like? Geese usually name ourselves after birds - I'm Robin, my grandmother is Kea, there's Heron and Tern and everyone knows a Raven and a Magpie or two..."

"Hm... Dunno I'm very a bird... What're other names like?"

"Huh... I don't know much about other peoples' names," he glances at Alyssum, "What do fairies do?" 

"Flowers, mostly. Or other plants."

"Oh, plants, that's a nice theme! I can come up with some examples of those! Uh... camellia, clover, bluebell, snowdrop, thistle, thyme, anthurium, laurel... trees too, I can do lots of trees, hazels and alders and willows and hollies-" He's maybe bouncing a little bit. 

"Anthurium sounds less wrong than the others, but I'm not sure I'm a flower person... Though a tree might actually be nice. Maybe an orange one? Or an orange flower."

"Huh... I can't think of any orange trees off the top of my head - besides actual orange trees, anyway. Lots of trees turn orange in autumn? There's a lot of flowers that come in orange, though! Begonias and marigolds, zinnias and dianthuses, dahlias and cosmos, lilies - there's orange roses, too." 

"Hm... Marigold is pretty but I don't think is me... I like Dianthus, and Dahlia, and Cosmos."

"I think I also like the word 'Autumn' though. Is that a name?"

"Anything can be a name if you pick it. Autumn is a nice word. Should we call you that from now on?"

"Yeah! I'd like that."

"Autumn, then! Nice to meet you," he'd shake her hand but she doesn't have any. Anyway, "You were going to ask me one more riddle, right?" 

"Sure!" She hums, thinking. "I appear once in summer, twice in autumn, but never in winter or spring. What am I?"

His mind having been expecting it this time, he catches the trick - or at least a trick - right away, "Hah, you can't get me like that when I'm expecting it! You're - u. You, you're you," he giggles, and shakes his head, "Summer has one 'u', autumn has two 'u's, and winter and spring have none. Right?"

"Exactly!" She grins. "You got all my riddles!"

"Not all of them! You said you know lots, right? You have to come along, that was so fun! Maybe I'll even think of a few for you to figure out, if you ask me more." 

"Oh, that sounds delightful!"
