Or maybe temple will show the original seed phrase... @MadFishCommunity

Yes, you can reveal the original seed phrase when you click "reveal seed phrase". This seed phrase is the one that was initially generated when you first set up your wallet. It is important to keep this seed phrase safe and secure, as it can be used to access your wallet and any funds associated with it. It is also important to note that this seed phrase should not be shared with anyone, as anyone who has access to this seed phrase will also have access to your wallet.

Wdym? It will show the first, or the second (the one shared by all wallets)?

Yes you can do that
