Vampire Diaries star Sara Canning has revealed that Alaric will confess something to Jenna in tonight's episode.
Jenna has become suspicious about Alaric (Matt Davis) recently and Canning explained that she will continue to have doubts.
Speaking to TV Guide, she said: "It's very uncertain if the relationship is going to completely crumble."
Canning explained that Alaric will start being honest with Jenna, although she refused to reveal exactly what he will tell her.
"The confession is linked to what is more pressing on Jenna," she said. "She's obviously not asking about his vampire-fighting extracurricular activities."
Canning added that Jenna has some exciting scenes coming up, saying: "In the next few episodes we're going to see something happen that is really going to rock her world and have her question if she is in such a steady and stable spot as she thought she was."
The Vampire Diaries airs on Thursday at 8/7c on The CW in the US and on Tuesday at 9pm on ITV2 in the UK.
