Sabrina saw Luna run to her greenhouse and she follows her after. She looks like she gonna cry any minute now and that's why she follows her to the greenhouse.
When she opened the glass door, Luna was curling up and wipe her tears. She doesn't know what happened but she can guess that must be something's going on upstairs.
"Luna, are you okay, hun?" She softly asked and rubs on her back.
Luna did not reply to her as she only shakes her head and sniffles. After a minute, she looks at Sabrina and smiles. "Sorry, I'm quite emotional these days." She slowly standing up and ready to go again.
Sabrina did not push her to tell what's going on. Maybe she wants it to be a secret and all she could do is giving her a bright smile. She helps her tidy up her hair and wipe her tears. "You look good now. Shall we start making the cookies?"
