After that embarrassment at Titan Cliff, Zero finally got over it after a week. Merlin had been merciless with the teasing and in retaliation, the young doctor only cooked spicy dishes for his teacher who suffered greatly at the combination of wasabi and ghost peppers.
They called it a truce after that horrible incident and apologised to each other as an olive branch. Not a single word about it was spoken ever again. Zero was once more back in Arabesque waiting for news from the lab members in Half Moon Village. Wiser informed him that he shouldn't go on his final quest before receiving his weapons and Merlin agreed. Instead, Zero found himself helping Lovina and Merlin out with some of the alchemy books. When he was bored with that, he would drop by Steve's lab to check on the progress of the miasma converting device that Wiser and Steve were working on.
