If Laurel dies, it will really be obvious. When Tommy died, I really didn't see it coming. I was more expecting him to turn to the dark side. His death was a complete surprise.
But if their plan is to kill Laurel, they are not being subtle about it in the slightest. With all the speeches, her super rushed road towards redemption and the writers doing their darnedest to make her likable in the last two Episodes, after dragging the character through the mud for the majority of the season.
But then again, it wouldn't be really surprising that they lack subtlety with Laurel. They've never been able to write the character properly. When they don't know what to do with the character, she barely contributes anything to the plot. When they finall have an idea, it feels like they are pushing the character front and center, yelling "Look! We are finally doing something worthwhile with her!"
Then again, maybe Cassidy is partial to blame for it too. Because she really delivers the drama, no matter what material she has. I found Rickards' speech, and her being at the verge of tears, a lot better acted than what Cassidy did the last two Episodes.
