If u guys don't understand it well I shall explain it here (sorry for grammar)
Dan and Jemma had a daughter named Jenny, and 2019, Jenny was diagnosed with cancer in the blood, so she was alive for only 12 months in the hospital. After she died she found herself in a void. She thought she might end up on heaven nor hell, but she ended there in the void. She saw fire surrounding her she tried to escape but she can't. Then she became a guardian, her form changed and age differently. At the time of 2020, Baby Asher was born! she looked after him every night, after Dan and Jemma saw her, Dan requested her to leave. (the reason why is because they thought she's a demon who wanted to take their son to hell)
She respected her father's orders and left the house, baby asher was sad about it, so as he grew up he thinks that's his imaginary sister but little do he know its real 👀👀
Also she went on with her afterlife and be a guardian angel of asher
Boiii I'm getting abit motivated I guess lmao
