Listen, I really don’t want to make a big deal out of this
But honestly? The fact that whoever is wrting the novel decided to add Keith in there is pretty significant? Especially when you go back to the original scene and take the context surrounding this whole thing.
Season 2, episode 9, right after the events of Keith’s bom trial in episode 8.
Kolivan and Shiro are done discussing the plan to overthrow Zarkon and shake hands to show their alliance. As shown above, there’s no Keith in there, just Shiro Kolivan and Antok. Keith is actually standing a little far off and he looks miserable.
We know this is happening after the BOM trial and Keith has just learned that he’s part galra. It’s affecting him and Allura’s shown distrust of the galra at that point, while very understandable, isn’t helping him. But you know what makes Keith happy again in that very episode? The hug.
It’s the moment when Shiro shows he’s accepted Keith and still loves him, be it that he’s half galra or not. Shiro is still there for him.
And these words on the picture?
They’re all relevant to the entire BOM episode and its conclusion. Where Allura was distrustful toward the galra, Shiro was willing to trust them. Kolivan, Antok and Keith are galra.
Keith is inserted next to Shiro here to emphasize both the alliance between Voltron and the BOM but also the fact that for Shiro, Keith was still Keith depsite being galra. Shiro accepted Keith when Keith doubted himself.
So Keith’s fond smile up there? My guess is it’s a parallel to the one he got when Shiro hugged him. Because while Shiro, the voltron leader, showed his trust toward the BOM by shaking hands with Kolivan, Shiro, the character, showed support, love and acceptance to Keith through the hug. So Keith’s smile is directed at none other than Shiro.
It’s significant that Keith was added in there because it adds more to the canon we already have and emphasizes what we already got from Shiro hugging Keith after the BOM trial. It’s also all significant because once again, we get to see that the BOM episode were indeed about Keith AND Shiro. Keith’s reveal was important not only him but also to Shiro. It tested them as characters but also tested and reinforced their bond.
Just like we’re always pointing out that Shiro is important to Keith’s character, Keith is also important to Shiro’s. This novel is Shiro’s story yet this moment which should be Keith’s POV only is added in. Because it’s important to both of them.
Keith is standing by Shiro’s side and smiling because Shiro is there for him. He’s also standing there because he’s supporting Shiro’s decision and always got his back. This is Keith and Shiro and their relationship in a nutshell if I can say it like that.
And I love that the writers of the novel chose to emphasize this important moment involving them both by having them stand beside each other while the alliance with the BOM is made.
