He's glad Carlisle takes the plant, stepping back a few paces afterward to give him some space while he re-pots it and nodding once in understanding at his name. "It's nice to meet you."

Lance is more interested at what Carlisle had said first than in introductions, though. "What happened to them?" The plants that Carlisle lost, he means; it's not like he's seen the weather change, which makes sense since they're in a cave, so what might've killed the plants? Lance is not particularly good at gardening--he's never even had a plant, for that matter--so he's not sure what else could've happened to them besides weather changes.
