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.
Maybe there's an association between them I don't understand?
'there to find the rosters on display' is the wordplay.
I cannot really see how this works, but
'rosters' could be 'rolls' ('roll' can be a synonym of 'roster') and 'rolls' is located in the answer.
The remaining letters 'up' is a valid word which might be clued in a way I don't see.
This may be the basis of 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" .)
