It would really be an overstatement to say that Sophia was ready to leave for the final mission, especially in her condition.
She had so much to get done and settled but her sources and time was limited.
Rohan was going to get discharged soon but if she personally went to him, there was no telling what might happen to him if he saw her in her current condition.
There are but only a few things that could come to mind when one's precious sister was going about her day with a teary gaze, slightly awkward walk and an extra flushed face.
Hence, Sophia couldn't personally see to the transfer of Rohan from the hospital to the new house. The same went for Lillian who was in a much vulnerable state. Literally.
She might end up back in the ICU if she saw Luna at her current state. Her current physical situation did not allow for her to be stressed or shocked. Seeing Luna was definitely a big NO.
