It was just too hard to stay wary of Rathma. Tyrael found himself instinctively relaxing around his nephew as the days went on. Honestly, he wasn't a threat.
It helped watching him interact with the Horadrim. Their relief was almost physically palpable when Rathma finally came out of his week of being completely immobile. Even Tyrael had been starting to doubt that the nephalem really would recover, but then he'd gotten up like nothing had ever happened.
What also helped was the apparent beginning of a new seasonal tradition; obtaining various types of gourd, and displaying them. Tyrael had at first thought it a show of wealth, but soon concluded that it was simply a show of decorating. Those with more gourds, bigger gourds, and the most colorful gourds seemed to be the 'winners' of the ritual. However, those who only had a few were still admired.
Lorath was very insistent on dragging Tyrael off to go obtain more gourds. While they were not officially being paid for their work, slaying demons and investigating claims of hauntings was shockingly lucrative. They had coin to spare, and pumpkins to obtain.
The sheer multitude of gourd-types was starting to make Tyrael's head spin. As an angel, it was rare to encounter so many different types of one thing. Usually when they got it right once, they went that way forever.
But here, every time he thought he'd seen every kind of gourd to see, more would pop up.
It made him laugh aloud whenever someone brought him yet another kind of pumpkin or squash. He could almost picture his brother weaving them all into existence, probably trying to come up with ones stranger than the last. (And by the light there were some strange ones). Just one more thing to love about the world that angels and demons had created together - it's diverse flora.
More than one occasion found the former angel simply sorting through all the squash they'd obtained. The Horadrim had taken to displaying them inside their home as well, and Tyrael decided he quite liked this new tradition of obtain-and-show-off.
Tyrael also discovered, purely by chance, that Rathma apparently liked the gourds too. For an entirely different reason.
It had not occurred to Tyrael that the gourds were all edible.
It wasn't as though the nephalem were consistently taking-and-eating all the pumpkins and squash, which made it that much harder to catch him in the act. No, he apparently preferred to take one at random, skulk off somewhere, and chow down.
(Tyrael tried taking a bite out of a raw mini-pumpkin, and did not understand how Rathma was possibly enjoying eating these things.)
The first time Lorath caught their resident nephalem in the act of gourd-snatching, he had chased him down the halls, shouting and shaking his fists all the way. Watching his nephew simply run away from the young man, Tyrael felt any remaining worries in his heart fade. Rathma had a good heart in him. He was not a threat - unless you were a pumpkin it seemed.
It became a form of entertainment for their little commune. Several of them had bets going on of which gourds would get taken next, if Lorath could get to them in time, and whether or not Rathma would eventually stop. Tyrael did not participate, but he did enjoy their enthusiasm. Really, they had so many of the decorative squashes that taking one or two wasn't that big of an issue. He was quite sure both nephalem and human were simply having fun at this point.
To Tyrael's delight, he discovered that the pumpkins and squashes were far more tastier when properly prepared. He'd tasted apple pie before, but the texture had left something to be desired for him. (Though the smell had been utterly divine.)
Pumpkin pies though. This, he was quite sure upon tasting, was probably his new favorite food. Just the right amount of spice, and they stayed together nicely on the fork. He still would probably never understand his nephew's preference for raw pumpkin, but baked pumpkin was simply too good to be true.
Tyrael was quickly deciding he liked all these new gourd-based traditions.
