As the three stand outside he goes to open the front door for them to walk into his and her house. Looking at the girl and Cassie he figured they would be a good match for each other. So he smiles as the door opens and ask if "Orihime would you like to bring in Cassie into the house." He then looks at Cassie and ask would you like for her to bring you into the house? Maybe why the two of them hang out he could fix a good meal for the three of them.
