Bio: A native of the planet Tojana, "the Worrier" is an elderly member of that society. He listened to the Seventh Doctor when the Time Lord suggested that just because a massive tide was rolling in, life could go on. When seemingly all the rest of his society doomed themselves to drowning in one last orgy of self-indulgence, "the Worrier" joined the Doctor on a hastily-constructed raft.
The Doctor left "the Worrier" on the raft after the pair had located the Doctor's waterlogged TARDIS. He was last seen drifting off in search of any other Tojanans who might've similarly survived the tide.
