I can only presume there is a character called 'Harold'.

Harold has been in the show (despite a brief hiatus in the 1990s when he was dead) since the 1980s. He was married to Madge.

He is a good Christian, appears to be dying of cancer, and may be gay.
He'd be ideal to head off to Zim. I should write to the Neighbours producers. It'd lift the show above Home and Away. I believe there may be another killer in Summer Bay.

I don't watch either, but I know enough to work these things out.
