Hi there,
Firstly yes you can go to court and sit with your partner in the capacity of McKenzie Friend - to understand more click below -
FNF - McKenzie Friends
Secondly - the AQ is not relevent now as it has been filed and while you could have applied for a strike out at this point - it is not relevant now they have filed.
Thirdly - If you have not yet submitted the bundle then I would add this to it, however I am sure there is enough in there to go on if you have already submitted it.
If you are worried and would like to include it, then I would send it in with a covering letter to the court to be placed on file and send a copy to the other side informing the court that you have done say and asking it to be added as further evidence.
Hope this helps if in doubt post back
