Warning! Spoilers ahead for Green Lantern #8
In the latest issue of DC Comics' Green Lantern, Far Sector's Jo Mullein proves herself to her fellow Lanterns as their new leader. With the near-complete destruction of the Green Lantern Corps, the Guardians, and the Central Power Battery, Jo is one of the few Lanterns left who still has a charged power ring. As a result, she's assumed command of the Green Lantern Corps despite her unfamiliarity with Oa (the Green Lantern Corps' home base planet), and this new issue sees her forced to defend the new role that she neither wanted nor asked for.
Given the position of her former jurisdiction and its great distance away from Oa and the Central Power Battery, Jo Mullein's power ring was specially modified so that it wouldn't need to be recharged by a traditional lantern (the trade-off being that it's not as strong as standard rings). However, this meant that her ring didn't lose its charge like all the others when an unknown threat blew up the Green Lanterns' Central Power Battery in a massive explosion. Since then, Jo has taken command over the surviving members of the Corps while working to investigate this new and clearly powerful threat.
However, Green Lantern #8 from Geoffrey Thorne, ChrissCross, and Marco Santucci sees Jo having to deal with unrest from her fellow officers. Without their rings' power, the Lanterns want access to Oa's weapons vault, distrusting the United Planets coalition Jo has been working with since the Central Power Battery was destroyed. Furthermore, Jo's leadership is called into question seeing as how she's a relative newcomer as she'd never had to come to Oa before this current crisis. However, Jo defends her new role as Corps leader quite well.
Jo lets the surviving Lanterns know exactly who she is in this issue, and it's an incredibly powerful moment. Presently, she's operating as the entire active Corps while attempting to lead those who survived, all while trying to figure out why the attack happened in the first place. She's hasn't become a leader because she wants to. Jo Mullein is leading the Corps because there's virtually no one else available with a working power ring to do so if she doesn't.
The responsibility on Jo's Mullein's shoulders is massive. However, she seems to be handling it well despite the natural stress that comes with it. Furthermore, not only did the Far Sector Green Lantern defend her position to the Lanterns who remain but she also compromised, making sure that they had weapons to defend Oa as needed while also offering more transparency about her investigation. However, she did challenge them to start acting like Green Lanterns even without working rings (rather than continuing to sow disunity and unrest). As one of the only Green Lanterns with power left, the last thing Jo needs is dissent from the very people she's trying to protect.
