Gideon
Sensing that she might lose the warriors' focus at any moment, Gideon reaches out and gropingly finds the shoulder - she hopes that it's the shoulder - of Garnup next to her. From the others' perspective, the halfling boy reaches out and grabs something in the empty chair next to him.
This has been fun. Let's keep in touch, shall we?
A quick pass with his other hand, and a few short syllables, and the spell is complete. The same raspy voice murmurs in the back of Garnup, Etain, Raj and Gornak's heads.
That ought to do it. And don't worry - no one hears anything you don't want them to hear.
The halfling takes a pair of daggers out of his boots and drops them into a side pouch of his pack.

In case it's not clear, Gideon is casting Telepathic Bond. If Paran wants in on the bond, he just needs to post that he became visible at some point over the course of the afternoon, and I'll ret-con this post (if Krimm doesn't mind, of course).
