Hank Henshaw/Martian Manhunter/J'onn J'onzz - whatever you refer to him as, this is a character who has been firm, no-nonsense and extremely strong-willed during Supergirl's run to date. Whilst Alex Danvers had given James Olsen a heads-up here, it was still a bit odd to see the ever-stern Henshaw actually take orders from James when it came to allowing Alex to stay in Kara's proverbial dreamworld for a little while longer. Henshaw is somebody that has literally not taken a single order from anybody so far in the show, even from those classed as his seniors. Clearly Jimmy's charm isn't restricted to just working on Kara.
