Keith's Claws

"Another arm, the human one, tried to grip Keith but he was a split second faster and jumped out of Shiro's reach before turning towards him again.
What was wrong with Shiro? Was this some kind of PTSD flashback? Shiro had never attacked them before, only stared at the air in horror and been paralyzed in fear.
Something was seriously wrong."

Voltron has returned from a successful battle against the Galra Empire. Not unharmed but nothing a trip to the medic bay wouldn't fix.
Of all times, this is one of the worst ones to grow claws and get purple fingers. Especially when Shiro is still high on adrenaline and the rest of the team is elsewhere in the castle.
