"Reign" Season 4 Episode 4 spoilers suggest that the next release titled "Playing with Fire" packs more than just a political union between Queen Mary (Adelaide Kane) and Lord Darnley (Will Kemp). Though Mary sees a spark of a new form of relationship with Darnley, the question remains if she could trust another party again following the betrayal from someone in her inner circle.

The official synopsis released for "Reign" Season 4 Episode 4 revealed that Lord Darnley will surprisingly visit the queen in Scotland. See the synopsis noted by Cartermatt below.

"When Lord Darnley surprises Mary with a visit in Scotland, Mary sees a glimmer of a union that could be more than just political. Elizabeth (Rachel Skarsten) fights to gain allies in her favor and Catherine (Megan Follows) must work to get Claude (Rose Williams) back on track by finding her a new husband."

What remains to be seen is whether Mary would finally accept Darnley in the next "Reign" Season 4 episode. It can be recalled that the queen has been wary of giving her trust even to those closest to her because one of her advisors turned out to be a traitor. However, this episode might be the beginning of Mary-Darnley relationship if history is to be considered.

Meanwhile, Queen Elizabeth will still be working to attract more allies on her side as per "Reign" Season 4 Episode 4 spoilers. With her willingness to do everything in her power to keep Mary away from her throne, Elizabeth might not keep the end of her bargain with Gideon Blackburn (Ben Geurens) as pointed out by Entertainment Weekly. There could only be one queen and she will not let Mary take the title, apparently.
