I had a dream where the lions had corporeal holographic forms to interact with their Paladins. And it’s all hijinks and shenanigans [and Lance teasing Keith for how motherly Red is with him] until Shiro notices how generally unpleasant Red is with him.
At first he thinks nothing of it cause she seems just as dismissive towards the others, and Keith tries reassuring him that she’s just being herself. Until he brings up the whole leading Voltron subject with Keith again, then she’s a hissing growling menace and if it weren’t for Black and Keith, Shiro thinks he might have become her chew toy. Doesn’t help that all the lions can speak, cause everyone can hear Red calling him a “cub stealing meatsack”.
And of course he tries resolving the issue [can’t have problems in the Team, even if it lies between a Paladin and a lion that isn’t his]. But considering how temperamental and unstable the Red lion is? He doesn’t get a reasonable discussion “You want a successor? Fine! But don’t come sniffing at my cub’s direction and leaving him an anxious mess with your talk of potential death!” and really putting him on the spot and getting a faceful of sharp teeth “Funny how you feel absolutely fine with keeping this topic to yourself and Keith. Shouldn’t you be discussing this with the princess? After all, she seems like a more suitable candidate for Black, and I sure haven’t heard of my sister’s approval on the matter”. Then it’s just her dragging Keith away by the sleeve and him just turning to give Shiro a helpless look.
