[Yup. Ecthelion's doing a pretty good job at not laughing outright at the poor boy (chuckling totally doesn't count okay).]

I suppose I have a few minutes to spare, your brother would be most unhappy if I did not. [He jests, honest! But he is picking up his flute and attaching it to his sash before leaving the small room he shares with Glorfindel.]

I will be no more than a few minutes.

[A nice way of saying if Elladan leaves, Ecthelion will not hesitate to send Glorfindel after him.]
