found a grub, , , not that uncommon a thing or anything but , , , its following me , , ,
O+h dear... It may have imprinted o+n yo+u... O+r else its Lusus abando+ned it. It's no+t co+mmo+n, but it can happen.
what shitty taste this grub has then , , , abandoned or killed by some means or another probably, , ,

Might I recommend speaking to a Maryam about this, if you so desire? They could perhaps return the grub to the brooding cavern, or maybe even offer care advice if you wish.
Have yo+u co+nsidered taking it to+ wherever yo+ur nearest bro+o+ding cavern is, to+ let the cavern attendants kno+w where yo+u fo+und it, and ho+w it's behaving? It may just be a failed lusus imprinting, and they'll be able to+ find it a new o+ne, if yo+u bring it to+ them.
Just make sure that they're prepared to+ take care o+f a grub. They're quite a handful, and tho+ugh they are surprisingly aggressive fo+r their size, they're also+ incredibly vulnerable and can die o+ff quite easily fro+m simply being in the wro+ng enviro+nment, o+r no+t being kept warm eno+ugh.
