Episode 18 spoilers for "Blindspot" season 1 hint of Jane and Kurt finally confronting their feelings towards each other, as the promo trailer promises that "One Begets Technique" would be the most explosive so far.

Fans would remember that in episode 17, Jane and ex-beau Oscar hooked up while Kurt got intimate with Allison, his ex-girlfriend.

But those trysts apparently didn't change the fact that Jane and Kurt have intense feelings for each other. In the trailer, Allison sees Kurt embrace Jane and confronts him.

What does it mean for the relationship between Kurt and Allison, and Kurt and Jane. Will they finally act on those feelings on "Blindspot" season 1, episode 18?

However, before they may do that, there's a bit of business at hand. And that's to bring to justice a notorious lawbreaker.

"In order to capture a dangerous international criminal, Jane (Jaimie Alexander) and Weller (Sullivan Stapleton) are forced to collaborate with the only person he will meet: their former target, Rich DotCom (guest star Ennis Esmer). Jane must decide whether to risk hurting Weller by executing a morally questionable order from Oscar (guest star Francois Arnaud)," the story description said.

The synopsis of "Blindspot" season 1, episode 18 reveals more spoilers as it said:

"Jane (Jaimie Alexander) and Weller (Sullivan Stapleton) create an unlikely team with the FBI's ex-target as they work together to search for the threatening international criminal. Jane, on the other hand, has to make a difficult decision after she gets a suspicious order from Oscar (Francois Arnaud) that could put Weller at risk."
