I really like the ideas thrown out there so far!  My brain just decided to formulate one this morning so I thought I might put it up ...<br/><br/>I was thinking perhaps the chronitons, since we've determined that they're somewhat intelligent, use a very basic form of either telepathic or empathic communication (as in with one another) though they can sense us to a lesser degree.  And maybe, whatever a person's emotional state, or state of mind at the time of their being affected was lead to whether they aged or regressed.  For instance, maybe my character Ensign Cassidy was feeling like she had a bit more experience like a lot of the rest of the crew and that lead to the chronitons causing her to age.  Someone who regressed may have been thinking they wish they had more youthful energy, or maybe was enjoying a fond memory of their childhood.<br/><br/>This may also help present a solution when it comes to figuring out a way to communicate with them, and the fact that we have a Beta Zoid on board may or may not factor into it.<br/><br/>Anyway, just a thought as my mind seemed inclined this morning ^_^<br/>
