Gets there to find the rosters on display (5,2)
I believe the answer is:
rolls up
'gets' is the definition.
The definition and answer can be both related to change as well as being verbs in their -s form.
Perhaps you can see a link between them that I don't see?
'there to find the rosters on display' is the wordplay.
I cannot quite see how this works, but
'rosters' could be 'rolls' ('roll' can be a synonym of 'roster') and 'rolls' is present in the answer.
The remaining letters 'up' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for rolls up that I've seen before include "Appears" , "Arrives" .)
