Having dealt with all his personal matters, Sam found himself unable to avoid addressing the main issues facing them going forward.
With Alice having promoted him shortly before her disappearance, in addition to the base's Valkyries being loyal only to him, Sam has automatically become the highest authority of the forty sixth base.
When you consider the fact that the upper echelon of the Resistance has perished during Hela's attack on the headquarters, it wouldn't be an understatement to say he's the highest authority in the world right now.
He wasn't very happy about his new position though. It gave him what he needed for his future plans, yes, however being responsible for the remnants of humanity wasn't something he was looking forward to.
