Seam was ( and still is ) one of the few sources of comfort, stability, and happiness for Jevil.
But it’s gotten so bad that he genuinely couldn’t stop fearing that Seam would just leave them out of the blue ( even if it’s out of character )
He knows that they won’t, but that whispering in his ear is telling him otherwise.
Finding herself floating around her room, wondering if she’s done something wrong even if Seam had the slightest change in mood.
Fortunately, Seam would give him the conformation that they're NOT leaving ( though it’s too late, should’ve said that a 100 years ago )
