cal is such a good boy i love him!!
i would absolutely love for yakov to meet his droid, he'll be fascinated by the little dude. also there's so much potential for psychometry in yakov's inventory - his gun is the one he would have used to kill the tsar in his timeline, he has a copy of one of lenin's pamphlets that he had with him in the trenches, etc

and ofc the commonality of being very anti-tyranny should deffo be explored.... love that for them
