'will he' is the definition.
'Don' can be an answer for 'he'. I'm unsure of the 'will' bit.

'pass the nag's head?' is the wordplay.
'pass' becomes 'do' (doing is a kind of passing).
'head?' indicates taking the first letters (I've seen 'heading' mean this (head could mean the top letter)).
The initial letter of 'nags' is 'n'.
'do'+'n'='DON'

Can you help me to learn more?
