1) Is Mal Duncan an Authorized Guest or a Team member?

2) How long has Batgirl been fighting crime?

3a) Can Garth and Tula speak English? Everything spoken in Atlantis from just after the Aqualad/Aquaman conversation in "Downtime" was an English translation of the spoken Altantean I believe, so I'm curious as to whether Garth or Tula can speak English. It would be a shame if Garth couldn't even communicate verbally with Robin or Kid Flash.

3b) If Garth and Tula can speak English, did they know a fair bit in "Downtime" or did they only learn some in the months/years afterwards?
