The darkness continues to rise on Reign.

Chatter On Elizabeth's Shocking Discovery On 'Reign'

In a new promo for the next episode released on Friday, Mary receives disastrous news- she has been banished from the castle and has to leave in a matter of days. So what does this mean for the kingdom?

Whatever happens there, something else to expect is Claude about to get married, but she's definitely dreading her time at the altar. Then there's the matter of Charles and Narcisse when Catherine gets knocked with a question she may not have the right answer to.

Is 'Reign' Going To Get Canceled After Third Season?

Narcisse is also rising in the kingdom as Catherine gets caught in what appears to be an awful mess. Her ruling just lowers more and more. And then there's Elizabeth who's just as sinister as ever.

See the promo below.

Meanwhile, there's been some speculation that the royal drama may not see the light of day after the third season ends. In a previous report from TV By The Numbers, the odds of the series being renewed for a fourth season aren't great, but they're not terrible either.

As for other shows on The CW that have a better chance of sticking around, these include The Originals, The Vampire Diaries, iZombie, The Flash, Arrow and Supernatural. But one show that has less a chance of staying for one more season is Crazy Ex-Girlfriend, which hasn't been doing so hot with ratings.

Reign airs on Fridays at 8 p.m. ET on The CW.
