The 100 season 7 episode 12 is coming within a few weeks on The CW, with the title "The Stranger." There are only a few details as to what's coming within this episode, but the title suggests someone unfamiliar is arriving and could stir things up.

According to the synopsis of The 100 season 7 episode 12, Clark, Octavia, Raven, and Echo are struggling to deal with a new foe. It seems like this stranger could hype the story up, and his or her arrival could further challenge everyone at the Sanctum.

It remains to be seen who this new foe could be, but it's clear that Clarke and others will be tested because of this person.The story could, also, develop into something more, especially since the current installment serves as the series finale.

There are only 16 episodes in the final season. So, there's not enough time to introduce a brand new arc. Hence, the story of this new foe could be the central story of The 100 season 7 episode 12, giving us clear details as to how this stranger could impact the lives of everyone else.

Before this episode, episode 11 will be airing next week and it will focus on Bellamy Blake. He's been missing through most of the final season and no one knows where he is. But now, it looks like the character is coming back and could answer some of the questions, particularly his whereabouts.

The synopsis didn't give further details, but it raises the question of where in the universe Bellamy Blake is. He is one of the most essential characters since the series started. So, it only makes sense he is coming back before the story comes to an end.

Bellamy's whereabouts are unknown, and some even initially speculated he might be dead. Yet, it is clear that the character is still alive and returning. After all, he's the one who takes charge of the group as soon as they arrived on Earth.

Bellamy's absence has caused a huge amount of pain to other characters, so many would be delighted to see him coming back. He is a natural leader and not afraid to tell what's on his mind. Even though he is aggressive, he still has a soft side and a big heart.

The 100 season 7 episode 12 airs on Wednesday night, Aug. 19, on The CW. The episode is directed by Amanda Row and written by Blythe Ann Johnson.
