Sparkshower was such a pegasister that she actually had an argument with Glamerspear about resuming her shift once she got back from delivering Anon's letters. After taking over Sparks' job guarding her Very Important Pony -- who wasn't actually a pony -- for his meeting with the probationary criminal Songwell, Lily was perfectly content to keep it up until the four-o'clock shift change. Artemis was having none of it, though, and when she found out that Glam hadn't gone for a lunch break on account of the meeting time, well, that gave her the upper hoof in the argument; the pegasus had hit up the chow hall for a quick bite before reporting in, so she insisted on returning to duty. Even though Lily owed her more than just a few hours' relief for what Artemis went through for her -- and what she was, to an extent, still going through -- the unicorn could tell she wasn't going to back down.
