Pulling out her wand as she made her way towards the taller figure, Lily felt like there was something familiar about the man. As she got closer it became clear that the plant he was near was a Venomous Tentacula, which explained the defensive posture and slightly wary tone in the mans' voice. If Lily was going to be the one handling the greenhouses, this would prove a good test for her abilities.
She felt a little more confident after assessing the situation, striding forward ready to help handle the Venomous Tentacula. "Looks like you might need a hand with those," she offered casually, eyebrows raising slightly as she finally was able to get a good look at him.
"Severus?" she asked, almost not believing her own eyes. She knew he was here; he had even responded to the message she directed his way. She just didn't expect to run into him randomly. "You look well," she murmured with a soft grin. "I'm glad I ran into you, since I hear we're going to be working together in a way."
