It’s pretty hard to stay calm so close to the Season 2 finale of Revenge. Add in the massive explosion that’s about to take place at Grayson Global (with Jack Porter inside) and you have us in complete meltdown mode.

In this new sneak peek from the finale, we see Conrad Grayson closely checking his watch and signaling to a terrorist to detonate a bomb inside of Grayson Global, all while giving a campaign speech down the street.

We know that Jack Porter was heading to Grayson Global supposedly to pick up the laptop that Emily Thorne actually threw into the ocean. Basically, Conrad sent him right into a trap. And right before the explosion occurs, a blocked text is sent out to all of the members of Connie’s audience saying, “Long Live David Clarke!”

Could this explosion be pinned on Jack Porter as an act of defiance, once again alleviating the Graysons from any blame? Probably, but the real question is, will Emily get there in time to save her childhood sweetheart?

Revenge Season 2 finale airs Sunday, May 12 at 9 p.m. ET on ABC.
