For the first time in a while Apollo was feeling conflicted. It wasn't often that he found himself worried about one of the Mousai, however after his meeting with Clio he knew he would have to ask Terpsichore about the information he had been given. He truly didn't want his first time seeing the lovely muse in years to be diminished by the possibility that she wouldn't take kindly to him prying into her personal life, so he wasn't sure how he'd approach that little issue. It wasn't even like he would be commenting to tell her what to do, more like to just make sure she was being careful.
It was bad enough that he had already needed to reschedule once thanks to outside forces, the meeting would be starting off on uneven footing due to his need to apologize for having to break those previous plans. He was hopeful that they could have a quick serious conversation, and then move on to something more pleasant. It never really worked out that way, but he could always be proved wrong.
Hearing the knock, he smiled as he opened the door, gesturing for Terpsichore to come in.
