It’s not even the fact Shaun and Rebecca aren’t in the games anymore
Things change. I get that.
It’s the fact that they had been upgraded to be the main modern day protagonists in Syndicate, getting to lead the story all by themselves without Desmond, only to be completely removed from the series straight after.
It’s the fact that they had their characters expanded, between Shaun’s speech about living up to Desmond’s memory and Rebecca’s comments about her cousin who could be a Sage etc, only for it to lead nowhere.
It’s the fact that the last time we saw them, Rebecca was bleeding out in Shaun’s arms after taking a bullet for him, proving the depth of their devotion to one another and showing their relationship in it’s most raw form ever, only for us to never see the follow up.
It’s the fact that it’s been 3 years since we last saw them, and the fact that the ONLY time we’ve even heard of them since was a few brief pages of a Last Descendants novel.
It’s the fact that they had been staple characters from AC2 onwards, appearing in every game except Rogue (and Unity for Rebecca) but being referenced in the games they weren’t in, appearing frequently throughout Initiates, being given some of the Assassins most important missions, being on Sigma Team’s most wanted list, and generally being vital to the Brotherhood, only to disappear without a trace.
It’s the fact that they were important characters who were with us for 6 years, in all different forms of AC media, and who we felt attached to, and Ubisoft thinks it’s acceptable to leave them lying on the floor of a London vault forever with no resolution to their story.
It’s the fact they helped save the world, and they don’t receive an ounce of credit for it.
It’s the fact that they deserve better. And I won’t rest until they get it.
