Nex has a henchpony of some sort - Lakeweed. I'm not sure if she needs an APP yet, but if she does, I'll make one soon. c:
Lakeweed is a ghost pony that died via drowning, hence the watery appearance. Lakeweed is not her real name, she doesn't remember it, so Nex just named her. Lakeweed can't talk either, at least she doesn't remember how to, so she just makes eerie wheezing noises at times.
