One might take Calen for a jumpy character; the sort who when roused from his sleep greets you with a drawn weapon. No, he might appear absented minded and withdrawn, but his attention was almost always on the present and his surroundings.
"Calenethir" he mutters lightly, then remembers his manners, turns and extends his hand (Gray Elves had adopted the Human tradition of clasping at the wrist in salutations). "Calen or Lieutenant will suffice. It appears the local guard is giving Taskon a hard time...I wonder why..."
Only a little, Calen had his suspicions. 'Contraband' came to mind.
