Julien ran a hand through all that hair in a gesture that was a nervous habit he didn't realise he had. "Uhm, well, okay... we could speak very nicely to the Professor and see if she'll let us borrow a space in the greenhouse for some practical revision?" he tried a little hesitantly. He was sure that Alfie wasn't frustrated with him, but it still made him nervous. There was something else there though, something that felt like anxiety, like he had to make sure Alfie wasn't unhappy; it wasn't just friendship but he didn't know what else it could be.
