When Jennifer left the Everleigh family, she had raised Jameson for two years and Sarah for less than a few days.
At that time, she hated James so intensely that her hatred extended to the Everleigh siblings, James's offspring. Therefore, when she left, she felt no attachment whatsoever.
Seventeen years have passed, and Jennifer's mindset has become much more balanced. She can now recognize that the children are innocent.
A few days ago, she finally emerged from seclusion after breaking through to the Heaven rank, only to discover that her son had died unexpectedly.
What surprised Jennifer was that she did not feel much sorrow over this, because she had very little emotional connection to the son she had not seen for seventeen years.
If this was how she felt about Jameson, then it was natural that she had no feelings for Sarah, who was practically a stranger to her.
