[[OOC: Thanks for the info! I was just kinda guessing before xD.]]
Jemma wasn't sure if Ariana was listening to her or not. She wasn't saying anything that useful, really, just going on a bit. It was kind of obvious what had happened to Miss Diggory anyway, the blood and the arrow were pretty obvious signs.
Jemma watched Ariana working, intrigued. She had never been much good at Healing herself, so she was very curious about it. As Ariana cut the clothes from around the cut, she saw how deep it was. It was really deep. She looked at her watch and realised it was 2am. "Mr. Riddle, you can return to your dormitory now." she told him, cursing herself for not sending him to bed sooner. "If any teacher asks why you're up, tell them you were with me." she instructed him. She figured having his friend hurt was enough for one night.
Jemma nodded as Ariana told her to hold something to Miss Diggory's head. She picked it up, and did as she was instructed. She wanted to ask what she was doing, as she was very interested, but she didn't want tot distract Ariana when Miss Diggory was in this state.
