As for the favor, I have a theory, I've got a feeling he'll ask them to use that etherion cannon thing, to wipe out the dragons if eclipse doesn't work, kinda like a plan B. dickbolt will listen, but lawhore only will allow it if jellal agrees to being arrested and then killed, Jellal reluctantly agrees (but finds a lupol later). If I remember, the cannon takes about an hour or so, and during that, the dragons will be defeated, but the cannon can't be stopped, so jellal, after kissing erza and professing his love for her for the last time, flies upward with meteor and uses all of his magic to stop the blast and sacrifices himself for everyone. As many mourn, even kagura was moved and realized erza sheilded him cause of love, lawhore notes they killed two birds with one stone, prompting erza to be mad beyond anything. Jellal then reveals he survived (barely) due to some leftover dragon surviving and eating jellal during his rush to the blast and took most of the blow.
