How we cite our quotes:
They consulted their village priest, and the result was that Elizabeth Lavenza became the inmate of my parents' house--my more than sister--the beautiful and adored companion of all my occupations and my pleasures. (1.6)
Literally the only reason that Victor's family adopts Elizabeth is that she's pretty. Oh, sure, she's charming—but being charming seems like a subset of being pretty, not something separate.
Everyone loved Elizabeth. The passionate and almost reverential attachment with which all regarded her became, while I shared it, my pride and my delight. On the evening previous to her being brought to my home, my mother had said playfully, "I have a pretty present for my Victor--tomorrow he shall have it." And when, on the morrow, she presented Elizabeth to me as her promised gift, I, with childish seriousness, interpreted her words literally and looked upon Elizabeth as mine--mine to protect, love, and cherish. All praises bestowed on her I received as made to a possession of my own. We called each other familiarly by the name of cousin. No word, no expression could body forth the kind of relation in which she stood to me--my more than sister, since till death she was to be mine only. (1.7)
Victor sees that Elizabeth’s beauty is the reason people love her. Yet this seems to be the reason he loves her himself.
As I stood at the door, on a sudden I beheld a stream of fire issue from an old and beautiful oak which stood about twenty yards from our house; and so soon as the dazzling light vanished, the oak had disappeared, and nothing remained but a blasted stump. When we visited it the next morning, we found the tree shattered in a singular manner. It was not splintered by the shock, but entirely reduced to thin ribbons of wood. I never beheld anything so utterly destroyed. (2.9)
The natural world is at once beautiful and capable of immense destruction.
