Jaqen H'ghar and moribund

By Ikaros, in 2. AGoT Rules Discussion

Hello.

I've a question abount Jaqen H'ghar from Forging the chain:

http://www.cardgamedb.com/index.php/GoTCards.html/_/secrets-of-oldtown/forging-the-chain/jaqen-hghar-ftc

Any phase: Bring Jaqen H'ghar out of Shadows by paying the rest of his cost to choose 1 non-Army character in an opponent's dead pile that was killed this phase, and attach it to Jaqen H'ghar as a duplicate. Jaqen H'ghar gains the printed text, base STR, icons, traits and crests of that card. If that duplicate leaves play, return Jaqen H'ghar to Shadows.

What happens if Jaqen is killed and cannot be saved?

Does he become "moribund" and "in the shadow" at the same time, and then first player decides?

Or, "moribund" occours first, so the static " If that duplicate leaves play, return Jaqen H'ghar to Shadows " never happens?

Thank you.

The duplicate leaves play after the card is killed (cannot be saved). We know it has to be "after" because the reason the duplicate is discarded is because the card it is on leaves play. So clearly, the card it is on must leave play first. Since Jaqen is already "moribund:dead" when the duplicate leaves play, he cannot be returned to shadows when the duplicate leaves play.
