Day 18: Ideas that should have been used more

So. Many. Options for the original question. And they don't even all involve Avon and/or Blake. I'm going to answer the new version from vilakins instead.

One thing I would really like to have seen more of was Cally's telepathy as something other than "taken over by alien of the week". It's used occasionally in situations where it's obvious just how useful it is as a way to give a silent warning to the others.  In Bounty:

CALLY [V.O., telepathing] Guards! Don't speak or make a sound. [Blake quietly crouches beside her, and they watch as the guards confer and then depart.]

CALLY My reflexes are dull. They almost fell over me before I heard them.

BLAKE I've forgotten how useful telepathy is.

CALLY Oh, I must practice that, too.

Yes, Cally, you must. Presumably you did, given that in Star One a telepathic warning stops Avon getting caught by a horde of not-hairy aliens and he manages to catch Travis instead. It isn't the only other example of telepathy being useful, but there seems to be a lot more screen time devoted to "Cally is taken over by aliens because she is a telepath".
