Perhaps if Boromir is observant, he'll realize that he's being studied back - big blue eyes, so dark they appear black at first glance, just barely above the water-line. Ilde isn't interested in getting caught in battles before she reaches Raven's Gate and her own territory, but it pays to know what's going on and this is not the first time that she's used an ability to move through the water for something like reconnaisance.

It's always an interesting experiment in stifling instinct; luring humans into the water is mischief more than anything else, most of the time, a gleeful pay attention to me! from the fey creatures that lurk there, but now's really not the time to start playing games with people who are heavily armed. Or anyone, for that matter, since she's got more important things on her own mind, like 'not dying'.

(The mind is a tool; Ilde's could really use a manual in a language she knows how to read. And a psychiatrist.)

If her eyes don't catch his attention, the death-shriek of the monkey whose neck she just snapped might do it.
