[Arthur will be checking up on those close to him - to make sure that they're alright and unhurt, now that the storm has passed. If he's noticed the changes in Kiseki, he's ignoring them for now in favor of finding everyone again and making sure they have their rooms and supplies in order.]
[But, upon returning to his and Merlin's room, Arthur will find a little Usyagi waiting for him, holding a flower-note for him. He tries to get away from it but eventually he absorbs the message like in the picture linked, and the message is a congratulations on acquiring a new flower shop.]
[... Which. why on earth would he ever want that.]
[If you check in on him in his room, he'll likely still be going "???" about it, but he'll also set out to try and find this shop that's being talked about in the note... so anyone exploring around Kiseki is welcomed to see the incredibly bemused Arthur staring at what is, indeed, a flower shop.]
