Blue Old Friend

The blue lion won't respond to Lance and he doesn't understand why. Every time they go on battles blue won't respond to him and whenever Voltron is being formed Blue doesn't respond. Lance doesn't understand at all, he tries bonding with his lion because maybe his lion and him need to get closer. Lance bonds with him but nothing changes or progresses. Lance is not giving up on his friend. He wants and will find out what's going on and he won't stop until he gets answers or figures out what's happening,
