Literally everyone on Team Voltron combined, all activating their bayards at once to amplify their bond and screaming Shiro’s name in unison: Shiro appears briefly, flickers in and out of focus and is scarcely able to communicate a few words, hardly able to materialize at all,,
Keith alone, calling for Shiro and just willing himself into the astral plane by sheer force of will: Shiro completely materializes, is able to interact with Keith and move freely, makes physical contact with him, speaks clearly, is able to pour his quintessence into Keith and share in Black’s power with him
And as Shiro said, he’d tried communicating with the others before, but he failed. This was something only ever possible with Keith–and even then, only because of how close they were. “I tried to warn the others about the imposter on Olkarion, but our connection wasn’t strong enough.” That Keith was able to do what every other paladin together couldn’t, that his connection with Shiro ran that deep–it speaks volumes, and it’s a thread of fate powerful enough even Haggar knew to fear it. There’s a reason she needed Shiro to eliminate Keith. “The Red Paladin’s connection to you runs deep. Deeper than the others.” Together, they’re unstoppable.
Keith’s bond with Shiro is literally deeper and more meaningful to him than everyone else on Team Voltron combined.
Gone full circle with this one
You should know by now, the What If’s will always haunt you, no matter how you try to push them away.
