Atlan didn't know how to thank her.
When he first met Tulip, he struck up a conversation with her, not because he wanted to, but because he needed to.
Carmine told him that Tulip was an important weakness of the creature in the castle, so he needed to gain her trust.
So, he talked to her and gained her trust.
It was nothing more than a job.
But now, she gave him something extremely special.
For Atlan, the amulet was just a piece of accessory, but for Tulip, this amulet wasn't just anything; it was the only surviving piece of object that wasn't burned down in the wreckage. She could have kept this amulet to herself because it was the only thing that tied her back to the home that she once had.
But because she considered Atlan as someone special, she gave him such a precious object.
Just as he was about to say something to her, Ninth suddenly shouted towards the group.
"Incoming!" she warned.
