Jen, her grandfather, and the scar
It is a scene from the pilot that might seem unassuming, yet remains crucial for Jen—and one I personally find magnificent. It is the first day of school, and Jen is getting ready for high school. Before leaving, she enters her sick grandfather's room to speak with him; she appears both deeply moved and fascinated by his scar. She even touches it ever so gently—a striking moment, as Jen looks like an angel, yet she is not afraid of that sight.
I love this sequence because it reveals so much with so little. First, there is the fact that Jen seems very close to her grandfather—likely much closer than to her grandmother at this stage. She does not hesitate to touch his scar, and generally, one only shares that kind of physical ease with people one loves deeply.
There is clearly a history of a deep bond between her and her grandfather—a bond perhaps so strong that it somehow prevented Grams and Jen from truly getting to know one another.
Another vital point: Jen seems fascinated by the scar. It is unsettling because she appears to "recognize" it, as if she bore the exact same mark herself. As if that scar were the perfect physical reflection of the deep wound she carries within. As if she were saying, "In my own way, I am just as damaged as you are, Grandfather." This clearly foreshadows everything we will learn about Jen throughout the series—her past, her demons, and the traumatic origins of it all.
