Awesome! Well, they're going to collect some of the plant life in order to take it back to Kyle so Jolene can inspect it. Edit: Nevermind, after coordinating with Jay we decided it's just as easy for this trio to deliver the plants to Jolene/the other mages, so they'll be doing that!

As for the worm, they're going to opt to keep it alive at first to see if it turns into anything. They'd make the castle authorities aware of this as well, even if it's just asking some lower level mages to get them a terrarium-like container for it and then having a protected area to store it while they observe what it does.
