I'm not sure if there is a publicly known romantic love story between Daryl Sabara and Meghan Trainor. They may be just friends or colleagues in the entertainment industry.
It's a bit hard to say for certain. Comics can sometimes leave such aspects open to interpretation, and it might not be explicitly stated whether Larry Trainor is gay or not.
Often, their close friends might be popular characters. For example, those who are part of their inner circle could be included to show support during the pregnancy. Another could be some fictional royal advisors who give them advice on royal traditions related to pregnancy.
The movie 'Meghan Is Missing' is based on a fictional story, not a real - life one directly. It was made to seem like a 'found - footage' horror film about a girl who goes missing. However, it contains disturbing and often unrealistic elements for the sake of creating horror.
