'Shadowhunters' season 3 episode 14 preview: Is Clary finally moving over to the dark side?

Spoiler Alert for 'Shadowhunters' season 3B

Ahead of the release of 'Shadowhunters' episode 13 of season three, their official Twitter account offered a ray of hope regarding protagonist Clary Fray (Katherine McNamara) finally being done playing the twin with her evil half brother, Jonathan Morgenstern (Luke Baines). But looking at the new teaser clip for the upcoming 14th episode, things don't look that simple anymore. On the contrary, at the end of the short clip, Clary utters something absolutely unimaginable, and if she's being honest, there's grave danger coming the to the Shadowhunters.

As the action peaks in the second half of the third and final season, a lot of loose ends have been tied already, within just three episodes. Clary is back after disappearing from the Mark of Cain explosion, but Jonathan — the prime antagonist of this season — has already tried manipulating her into joining him in the dark side. We saw Clary try to reason with him, as the two of them pretended to be Italian and toured around Paris, but it wasn't long before Jace Herondale (Dominic Sherwood) — the love of Clary's life — found her and brought her back. Naturally, this had managed to spark a rage unlike any other in Jonathan as he felt betrayed by the only family he has and he promises to make them pay for it.

Signs of Jonathan's rage were exhibited in the last aired episode 13 when Clary reveals the new rune upon her shoulder that she shares with Jonathan now, and soon enough, writings in the form of burn marks start appearing on her skin.

This proves that the newly developed bond that Clary and Jonathan have been connected with, gives either of them the capability to feel what the other is feeling. In that, by wounding his own self, Jonathan is also able to cause Clary immense pain, and worse, make the same exact wounds appear on her skin.

 

Still, all of this would have been deemed under control, had it not been for the final seconds of the new trailer for the upcoming episode. After indulging in sharing her much deserved moments and also a date night with Jace, Clary can be seen in the presence of Jonathan in what appears to be his apartment. As if the idea of it wasn't dangerous enough, Clary actually ends up telling her evil brother, "To play Jace's virginal little girl again, got real over real fast. I missed our time together." Shocking, right?

Not as much as all the potential plots that could pan out from this. Is Clary being an ace strategist once again and trying to trick Jonathan so the Shadowhunters can finally kill him? Or was she putting up an act with her Shadowhunter friends all along just so she and Jonathan can finish them off? In the official trailer released ahead of the mid-season premiere, one of the biggest takeaways was a scene where Clary opens her eyes and they are pitch black, like a demonic entity. So is she truly moving over the dark side or is this development just a price she's paying for her end goal of finishing Jonathan?
