Some of this comes out in the third ep and I think if they continue on with this, it will make for an agreeable outcome. Dylan is the expert on the Andromeda and the Commonwealth - Bekka is the expert on the here and now. Basically on equal footing. Dylan is also military trained and so on missions requiring that sort of leadership, Dylan takes the lead.
Each of the other crew have their own specialities that are joined in with working aboard the Andromeda with Dylan the actual 'leader' of the group but everyone else stepping in when what is being done has bearing on their particular specialty.
Of course this all may fall apart with the 4th ep. The previews sounded more than a little interesting.
Cheers,
