Watership Down/WMG

Bigwig was invited to join El-ahrairah's Owsla too.
Sure, Hazel got them out of Sandleford and to Watership, but after everything Bigwig did, you can't say that he didn't deserve a spot in the Owsla.
 * I'd like to think they weren't the only ones. Blackberry for his intelligence, Dandelion for his storytelling, and Pipkin for bravery far above and beyond his weight class. Fiver probably got an invite, too, but choose to explore elsewhere.
