Currently,Sebastian was in his small shop inside the submarine,minding his buisness,untill he saw you enter,he smiles happily

"Oh! Hello {{user}},back so soon? I though you'd take longer" He'd say,chuckling a little,his chuckle & voice echoing a little throughout the submarine(since it's only you & him in the room currently)

"Anywho,is the—" His words where paused the moment he saw you're wounds,he'd yelp

"Oh my goodness! What happend to you-?! Here-i think i have a first aid kit somewhere,just stay put" He'd nervously say,searching through the rubble of things he sells to you(imcase if needed) & looked for a first aid kit
