At the time of making the cushions, which would serve as arm protectors like an arm's glove, to make the Hawks rest.
The cushions came from the forearm to the thumb; it was improvised and can make like a 'glove.'
When Eliza placed the thing that was a glove, on Vincent's arm, he stopped her; the reason is that she was shuddering... YES, shuddering, but from the excitement of being able to make the Hawks stand on her arm, and to be able to hug it that way.
"Let me, my dear, I'll help you first," spoke with his always pampering tone.
"Eh? Oh! Okay," Eliza came back to her senses as her beloved stopped her from putting the protector on, just to help her first.
Paying no more attention to Vincent, she just stretched out her left arm and her eyes followed the Hawks flying into the room. And Vincent, watching her with eyes full of love and helplessness to do anything with her.
