"Forget it, I will go upstairs to check in on Lowell first." In the end, Grace couldn't wait any longer. After all, everyone was in a relationship. Lowell was the only one alone, and it seemed like he was lonely.
Understandably, Lowell was raised by his brothers and sister, and Grace felt that no matter how well she and Heinz treated him, it would not be as ideal for him as compared to growing up with his parents. After all, Heinz and herself were not Lowell's parents.
When comparing doing someone a favor and fulfilling obligations, he would be more restrained when he was receiving a favor from them. On the other hand, parents were obligated to take care of their children, and he could have been relieved from scruples, as there would have been nothing for Lowell to fear of.
Over the years, Grace understood that even if she tried her best to take good care of him, Lowell would still feel like he was living under someone else's roof.
She could empathize with his feelings.
