Vervain aka Chervil is a cowardly and sneaky rabbit, more adept at spying on others and threatening the weaker ones then in actual combat and is (next to Woundwort) the most hated and despised rabbit of the Watership Down story. Despite his shortcomings, Woundwort values him (though he would not show this) for his loyalty to him. Although Campion saved his life on more than one occasion, Vervain hates him with a passion and would like nothing better than to make Woundwort realize Campion is a traitor. Kehaar is particularly not fond of Vervain and calls him an 'ugly bunny'. After Efrafa's destruction, Vervain tries to live on his own but quickly loses hope, until he is saved by Woundwort. Although somewhat shocked by his master's increasing madness, Vervain continues to serve him, though more out of fear than respect, and he secretly longs to lead a different life, even if such thoughts are futile.
