"Well… I hate it! I don't want to be an egg! Where's my big body?! Ugh… I shouldn't have helped you!" Ignatius said with a tone of anger. However, I couldn't really take a floating egg seriously.

"R-Right… but even then! I… am I really becoming a Spirit?" he wondered.
Apparently, something triggered this change in him. Alice speculated that fusing with a spirit ended up filling him with spiritual energy, which ended up becoming permanently added to his very soul. With that, his soul slowly mutated into a spiritual soul after he was weakened, only having this leftover energy to assimilate and make himself whole. However, he lacked the strength to become a big dragon, so he ended up regressing back to a spirit egg.
