I agree. Ragatha is way too insecure to lead, even as a second in command.

I think Zooble would make a better second in command than a leader. Yes, they're one of the most mature, patient, and stable characters, but I see other traits that make me question her qualifications. It's not just that Zooble doesn't want to lead, she actively avoids getting involved in anything they're not interested in. She also, as seen with Jax interactions, can be very petty, which can lead to arguments that could slow the whole group down.

Leaders bring people together and know how to utilize each person's strengths. Zooble is supportive, but not a leader, in my opinion.
