I just feel like Sam has a lot that suggests he could get more focus - clearly Pike knows him fairly well (again seen in E9), and the others too. I hope we do get more with him - but I am glad the show has foregrounded other characters more. Too few episodes, overall! I miss 26 episode seasons so much when it has come to this show, but equally I know that the limitations of this season's length have probably helped make it so good (and ensured more budget per ep).
