I've just perused some of the 500 raw images
taken by Cassini over at its website.
I surfed over onto #23 batch, that contains IR
images of Titan's surface.
One of the images has a bright linear feature; SW quadrant?
And that linear feature looks like it may have brightness consistent
with a liquid reflecting sunlight.
I'm not going to hold myself to that interpretation, because?

Because I'm not sure how sunlight would look reflected off a liquid on Titan with its cloudy, hazy atmosphere.

Wouldn't the reflected glare be diffused by the haze?
In fact, wouldn't sunlight be diffused to a point that you only get
a bright patch on the liquid at best? [Think of flying over a lake on a cloudy
day and trying to see a reflected glare off its waters].
And if it's foggy near the surface, wouldn't the glare off a liquid body be even more unlikely?
I won't even hazard a guess.
