Please excuse my ignorance but this isn't the first time I've read about the third eyelid but I don't know what that is. I can see that Sir Lawrence's eyes are runny and they appear swollen to me but I can't see a third eyelid or is that just an expression?

I sure hope you're able to do something for him, Gary, the poor little guy. At least he got a meal from you, Mr. Kindheart.
