Good news for fans of the NBC show Constantine as last night's mid-season finale saw a ratings spike.

The episode "Saints Of Last Resorts" was up 25% among adults in the coveted 18-49 age demographic compared to the previous week.

3.30 million people tuned in.

NBC has yet to officially announce a second season for Constantine, but Angelica Celaya, who plays Zed, recently hinted at a Season 2.

Though NBC didn't order a full season, Celaya stated the remaining episodes of Season 1 will be pushed to Season 2.

A #SaveConstantine campaign is underway as well, which actually was trending on Twitter for a while.

Constantine airs Fridays on NBC.

Here is a preview for the next episode, which returns in early 2015.
