Their entire plan to take down Zarkon had gone sideways in the absolute worst way; shutting down the entire ship had gone rather well, which was good, but when Haggar had stepped in, that was when things had gone utterly quiznacked.
A surprise hit from her and a follow up one from Zarkon in a special mech attacking Black and Voltron was split apart violently, with Black (and Shiro) temporarily knocked out. The other paladins fought him off the best they could until Shiro woke back up and they recombined into Voltron.
At least, until Haggar hit them again with more of her magic...
She actually leeched a considerable amount of quintessence from them, knocking out both paladins and the giant combined mech itself, although with a bit of encouragement from Allura, they managed to get Voltron powered back on again utilizing their bond with each other and the Lions.
When they did, they managed to beat Zarkon, piercing his mech through with the sword Voltron summons --
The resulting explosion, however, forced the Lions to split from Voltron and shrapnel to be thrown everywhere -- with one particularly big piece stabbed directly into Black, and the paladins worried considering Black also went out of commission at the same time...
The other Paladins didn't think twice about it, immediately getting Black and taking her to the Castle, then landing their own lions and bolting straight for Black. Lance's own stomach was twisting to the point he wasn't sure what was worse, that or the absolute worry he felt.
What met them was a sight that had all of them horrified -- the shrapnel had indeed jutted straight into the control room, directly into the pilot's chair -- and Shiro along with it.
And judging by the amount of blood.... he definitely didn't survive.
Pidge bolted out of the cockpit and it didn't take a genius as to what they were likely doing in the other room, and Lance had to admit, he wanted to do the same, but he forced it down. "C-Coran-- CORAN."
