I really actually intended to do this one (especially since it was my topic to begin with) and I'm sure that this has been the case for more than one of us with more than one topic.
Could we perhaps do a Make-Up Friday? I know that it's also Topic Friday. Maybe the Topic could be posted with "Topic" and makeup posts with "MU?" Or maybe we just add a makeup week to the rotation where we can choose whichever topic we've missed (maybe in the always-prompt-Cassie's case she could do whatever she wants since she's never missed anything).
