The tension between the two ladies has been brewing since Season 1 started, as per Yibada report. Here is the complete synopsis for Episode 10:

"Clary and Jace get a tip from Meliorn that they can find Valentine by locating a portal in another dimension, but only Clary can venture into this new world. What Clary finds in this alternative universe is that life there is as if the threat of demons no longer existed and Shadowhunters were no longer needed," as the summary went.

"While she realizes that this dimension is the life she always dreamed of, Clary must act fast or she will lose herself in the alternative world forever. Meanwhile, Alec and Isabelle must face the consequences of the Downworlder attack."

As for the video released on Youtube, the teaser began with Lydia announcing the arrest of Isabelle "Izzy" Lightwood for "high treason" upon the Order of the Clave. Then, Alec was surprised and asked Lydia for a more concrete reason, to which Raj made some remarks about Izzy's "escapades.

For that, Izzy addressed the threat by telling Lydia that she is no better than Valentine by saying that that latter had the guts to say to the Downworlders that he wanted them all dead.
