What could be the possible plotlines in a D Gray - Man fanfiction where the Earl hugs Allen?

The plot might also be that the Earl's hug is a way to get Allen on his side. He could be trying to convince Allen that there is a different path than the one he's currently on, and this hug is the first step in that persuasion.

There could be many interpretations in such a fanfiction. Maybe the Earl has some complex motives behind hugging Allen. It could be a moment of false kindness, where he's trying to manipulate Allen in some way, perhaps by making Allen lower his guard.

Perhaps a plotline could center around the Innocence within them reacting to the pregnancy. Maybe Lenalee's Innocence has some sort of special reaction, like providing an extra layer of protection. And Allen could have dreams or visions related to the future of their child, which could lead them on a new quest to understand what it all means in the context of the D.Gray - man world.

Perhaps the Earl discovers Allen when he is in a vulnerable state. The fanfic might explore how the Earl's presence affects Allen's development. It could also show Allen's internal struggle between the kindness the Earl might show him and his loyalty to the Black Order. It could be a story full of psychological drama as Allen tries to figure out the Earl's true intentions.

Isolation is also a theme. Allen is often alone in his struggles, being the host of the 14th Noah. Fanfics may depict his feelings of isolation from both the Exorcist side and the Noah side, and how he copes with being different from everyone else.

Maybe he discovers a new form of Innocence or a unique way to use his existing powers. These fanfics often add exciting new elements to his character development.

Maybe the Earl hides Allen in a parallel dimension where time moves differently. Allen has to find a way to get back to his own world while also dealing with the strange rules and creatures in this new dimension. The Earl's motives for doing this could be to keep Allen away from the Order and use his power for his own evil plans later.

There could be. 'D.Gray - Man' has a large and dedicated fan base, and fanfiction writers often like to take the story in unexpected directions.
