Nothing, you have to start over again.
if you saved after you lost then you have to start the game over, that happened to me.

If you are defeated by N or Ghetsis in the Plasma Castle you are sent back to the Pokemon Center at the Pokemon League. You can then either leave and go train, or go back to face N or Ghetsis again. To return to the castle, speak to the team plasma member standing in the Pokemon league Pokemon Center.
yes and go to the Pokemon centre near the Pokemon league talk to the team plasma guy and he will take you to ns castle

In the Pokemon League in the Champions room.
Sorry, but N disappears after you battle him and Ghestis in the Pokemon League.
You can catch Reshiram only in Pokemon Black, when you are about to have a battle with N in the Pokemon League.
if your talking about the primary ones (zekrom, reshiram) at N's castle; after the Pokemon leave N's castle gets attached to the league. then through a series of fights you can catch zekrom or reshiram. :) - after the Pokemon league.
Ghestis disappeared after you battled him and N at the Pokemon League.
train good pokemon that's all you can really do
he is at the pokemon league after you beat all four elites and N
beat the Pokemon league and beat N and you use your Master Ball to catch him
