...And then the loud sound of a trash can crashing into the ground startled Lucy and drew her attention. ...A boy had rolled out of said can. She just sort of gave the scene a skeptical look before deciding that the crying child once again took priority. She totally strolled right on over, past Ryan without so much as acknowledging him, and moved to Amethyst. She would then bend over to pick the smaller girl up and just sort of hold Amethyst against herself. It was a comforting, arguably adorable embrace, a natural mother's embrace. She completely disregarded the fact that Creed was right there. This was not rude to her. It was conflict avoident. She merely turned to acknowledge his presence after picking the smaller girl up.
Meanwhile, you could totally still imagine her cursing repeatedly in the privacy of her own mind, very irritated with the situation.
