Nicodemus had no idea what was going to happen and that alone was freaking him out. He certainly wasn't expecting anything more than maybe, at the very most, handholding, certainly not a kiss and anything else, well. Still, it was his first real 'date' though not a date as such and it was the first guy he'd really liked in a way that was more solid than mooning over Quidditch players or young male Wizard authors in book jackets. He was so nervous he felt sick but he'd worked hard on the picnic basket (he'd driven the Elves into a frenzy with his tweaks and changes until the contents of the basket were 'just right') and he'd brought the blanket he'd tried to charm for them to sit on, the one where the colour still slipped around like a duck on a frozen pond.
He'd made it cosy, snuggled up against a tree, cushioned underneath, charmed to be warm, spelled to repel the damp with a nice view of the lake itself without being too close to it's edge. He was happy with that, and he'd got everything set up inside the basket waiting to be laid out.
Looking out for Jack he saw the hair first and sat up, watching the older boy approach and then standing to wave him over. He'd hoped to play it cool but he couldn't stop the smile on his face; he'd really, actually come! He waited until the other was in earshot before speaking.
