[He smiles at Pegasus as he greets him so politely.]

All's well, thank you. We're about to embark on an underseas expedition.

[He turns to Medusa as both of them continue to pet her mount.]

You bought an Animal Amulet too? It may help us underwater.

[He isn't noticing her hesitation, completely focused on the mission ahead and seeing this little moment as a courtesy to Pegasus - he does deserve to be the first animal Medusa speaks to, being part of her Noble Phantasm. Speaking of which, he has something to say to him, too.]

Pegasus, thank you for the good work in the battle against those wyverns. You saved our lives back then.
