[Lyle hadn't been quite sure what to do for a "superhero party". There wasn't really anything pre-set. It was flexible. So in the end, he ended up pinning a large letter "L" to the front of his shirt. Seemed simple enough and effective for the purpose of the party.
He hadn't been quite sure what he was expecting, but it definitely was clear that the host of the party was a teenager. It was rather juvenile, but given the age level that made sense]
