Two characters discussed — one's pretty (5)
I believe the answer is:
cutie
'two' is the definition.
Both the definition and answer are singular nouns.
Perhaps they are linked in a way I don't understand?
'characters discussed one's pretty' is the wordplay.
I cannot really see how this works, but
'one' could be 'i' (Roman numeral) and 'i' is located in the answer.
'pretty' could be 'cute' (both can mean attractive) and 'cute' is found in the remaining letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for cutie that I've seen before include "Smart female" , "Attractive young woman (slang)" , "Endearing person" , "Smasher" , "considered by most to be attractive" .)
