OK, considering this will be a series of movies, think like a movie writers and what will keep people interested and the movie makes perfect sense. Would you watch a trilogy about a crazy junkie, me either.
Here's what happened;
Abigail, the young girl is a bio-experiment, she requires those shots to survive. The "father" and maid are her caretakers. Her strange behavior, shots and hat are explained by the fact that she is a lab experiment. Her "father", who she never once calls dad, is just a caretaker, he gives her shots, and records her vitals on his laptop. He has no reason to show her compassion, it's not his daughter, and he's not molesting her.
Maggie is from the future. In the future, just like today, songs are REMAKES of older songs. So considering she said that not everybody has access to technology tells us that it's possible someone in the future re-sang the Cranberries song. She wants to see her mother (Abigail) because she knows that to avert disaster, and starvation in the world she has to destroy her mother (and thus herself) which is why she tells her followers she will have to leave them soon. She is preparing her followers in case she fails in avoiding disaster.
The DOJ agent is from the future, she isn't sweeping her room for bugs, she is running water to cleanse herself of germs, like what is done to the followers, she is shutting off the heat and A/C to prevent germ filled air from flowing into the room, and in her gift box was a vile, perhaps she is giving herself shots to survive in the past.
At the end the DOJ agent is returning Maggie to the future which is why we see the ultra bright light.
