Her father died right after her 2nd birthday and although her mother loved her she was a bit ashamed of her daughter being an alien.
Marleen’s family is full of weirdos (witches, werewolves etc.) and she was the only "normal" person. She might have been envy of them but she never said so. What does she see when she looks at Nymphea? Herself, but with strange eyes. Who is capable of powers she will never have. Jealousy at its finest.
Her mother’s behaviour influenced her social interactions. She was shy and never talked to anyone at school. Maybe that’s why she fell in love with her imaginary friend. Thanks to her aunt Moira’s amazing skills Lycopersicon became a flesh-and-blood sim.
They now have two sons, Nipudus and Zorlack.
