Heh, honestly, no. But I'm pretty sure they will have some funny interactions together when we reach Elfhelm.
So far they have been solidly set to be the comical relief of that part of the story with their ongoing scheme.
Now to put another spin on this little subplot of theirs, I imagine this is an old age speculation, but does anyone think Puck might be connected to the Elf King or some Elf royalty? Say Puck the Elf prince?
