Titles with bite: The episode title comes from the well known phrase "Once bitten, twice shy."� Very apt for this plot.

Elder statesman: Melissa Jaffer (Noranti) gets to do the voiceover at last.� Obviously the saying age before beauty counts for little on Farscape.

Family business: Twice Shy writer David Peckinpah is the nephew of Hollywood veteran Sam Peckinpah, responsible for classic movies The Wild Bunch and Straw Dogs.

Guest spot: Talikaa is played by Paula Arundell, who has appeared, like many Farscape regulars, in Aussie police drama Water Rats.� She can next be seen as Simone in comedy thriller Bad Eggs, due out later this year.

Been here before: A couple of previous episodes are referenced here.�D'Argo reminds Chiana that she brought a troublsome Vorc on board in season two's Beware of Dog.� Later, when the crew realise that their minds have been messed with, they compare Talika to T'raltixx, who did much the same in Crackers Don't Matter.

Substance abuse: John refers to the extract of laka he's been using to forget Aeryn as poppers - the common slang name for the appalling headache-inducing drug amyl nitrate.�

Funny money: Rygel pays with dodgy�coins that look like 100 Krindars but are actually "a twelfth of that."� So that means there's an eight and one-third Krindar coin in general circulation around Scarran space.

Home comforts: John's eating chocolate - he obviously took care to stock up before going back in to space.

Missing mojos: Based on what Talikaa stole, the crew's strongest traits are: John - optimism, Aeryn - emotional control, D'Argo - anger, Rygel - greed, Chiana - sex drive and Scorpius - Scarran violence.

Below the belt: Weakly indicating the memory orbs in Talikaa's nest, John oddly refers to them as nads - a phrase usually used for a delicate part of the male anatomy.� It's also the name of a painful sounding hair removal system.
