Because of his space suit, of which he had just lying around for such an emergency and having time to throw on, he boards with Ethan on the ship.

The Grunt just looks up and shrugs, returning back to the Madness.

Meanwhile, unbeknownst to @tristancarax & @theironfelix, the were-squirrel trains with an army of ninja kitties.20181210_200750.jpg

Good thing I'm in space! haha

The Grunt just looks and does the only thing a Grunt would do: d'awws and cuddles all the ninja kitties with snuggles. All aggression from the ninja kitties drop as they play with the Grunt's jester bells and the Grunt scratches their lil' tummies. There's some truth to this adorable part of adorable killing machine... Like that one time, in the middle of a fight, a Grunt disarmed a crazed tango just by engaging in CQC hugs [cite incident #0219238 with Naked Snake engaging in CQC hugs with Solid Snake to effectively stop conflict in Metal Gear Solid 4], neutralizing the enemy with effective cuteness. The tango blabbered on, spouting their memories as they saw what happened to their other comrades who were annihilated; those same comrades who went on torturing the Grunts beforehand for hours on end. The crazed tango soon learned, post-battle, that Grunts hold no hostilities if yah never do ill-acts against their own.
