The 100 season 7 episode 15 is coming this week on The CW, with the title "The Dying of the Lights." This is the penultimate of the series and it comes with a lot of questions. Most lives are in danger and it remains to be seen whether or not everyone will make it out alive until the end.

Clarke (Eliza Taylor) is the biggest concern in The 100 season 7 episode 15. She wants to save all the people that she loves, but she may sacrifice herself in the process. The battle between the Disciples is coming and she has to find a way to win the war.

Clarke wants to save Madi (Lola Flanery), as well. The biggest problem, however, is that she doesn't know how to get out of her current situation. She lost almost everyone that she truly cares about and everything that happened has hugely impacted her life.

She's been doing everything she can to protect others, but she tends to hurt herself along the way. What Clarke needs to do now is to save herself first before saving others. A lot of lives are in jeopardy and she has to figure out how to protect the remaining people in her life.

She and Octavia (Marie Avgeropoulos) will do a rescue mission as the Disciples are getting closer to getting what they want. Since this is the penultimate episode, we could expect several twists and turns leading to the series finale.

Some of them may not make it out alive, given that the series tend to feature unexpected deaths. Fans have already seen the demise of Diyoza (Shelby Flannery) and Bellamy (Bob Morley) this season. No one is safe and there could be another major death before the show officially concludes.

Meanwhile, the promo of The 100 season 7 episode 15 featured the "one last war." Everyone is preparing for the ultimate showdown between the Disciples. The clip showed a lot of intense scenes, such as a near-endless amount of gun battles.

The penultimate episode will be challenging for everyone. The final battle between the two groups may not be wrapped up here and will continue in the series finale. It's yet to be seen whether or not all of them will get the happy ending that they deserve.

The 100 season 7 episode 15 will be airing on Wednesday, Sept. 23, on The CW.
