Tahlia would definitely prefer a very loosely democratic approach to things, but in reality, there's no rules, and Tahlia knows most of the crew is smart enough and has enough common sense that they don't really need specific rules, just an understanding that playing stupid games will win you stupid prizes.  The way she sees it, being as small as it is, the crew can effectively run with everyone having their own amount of autonomy, so long as everyone does their part.  More serious issues would undoubtedly call for the crew to convene and discuss it.

It's also worth noting that Tahlia is still reserved about assuming the role of a leader, per-se.
