He'd settle a paw over Roxanne's head to get her to settle down. He'd remembered visiting the cove once, briefly, in order to avoid Duskorna's borders when the weather was too poor to fly over. If he knew his geography, it would be quite a journey for Roxanne, and he wasn't sure she'd make it. But she seemed excited, and nothing grows stamina better than exercising. Still, he worried... "Alright, yeah, we could go now if you're up for it?" and on the matter of any supplies Larkspur needed, he'd wave a paw dismissively at it, "Herbs are enough. I only know a few basic remedies myself, if you can teach me something about herbs that a novice can't, I consider that enough. I assume you like the thrill of discovering things yourself? There is a type of leaf I've heard of that holds its own indentations... Supposedly, if you dry it properly and by just the right amount, you can use a rock or your own claws and it'll make marks that won't go away for a very, very long time. Is that something that might interest ya?"
After their talk was over, Matthias would check his satchel to ensure he had everything he needed. Roxanne carried her own satchel in there - who knows what she had in hers - so they should be all set to go, provided nobody had any issues. Assuming not, Matthias would take over, flying alongside Larkspur and making sure Roxanne stayed close to them.
