Huan is off in the garden somewhere. He was less interested in the salt water than Anariel was. (The timeline goes Anariel arrives at Elrond's, Anariel runs off to Tirion before Elrond can make any excuses about why they'll be staying at home a while longer, Anariel hangs out in Finwe's House with the occasional outing into town or visit to Mahtan, Anariel commandeers Feanor's workshop, Anariel decides she's had enough of Tirion for now and goes to see Elwing.)
