Spoilers of some degree in this description. You've been warned!
Okay, so after Colette becomes mute, she resorts to writing out words letter by letter on Lloyd's palm to communicate. This is not foolproof. I tried it on my friend's hand, and she often mistook letters for other letters and we generally messed up at first. Now, Lloyd is not a bright guy, and to top it all off, he's wearing gloves. Therefore, it's more than likely he'd screw up. A lot. O:
Poor Colette.
Maybe Lloyd is blushing in that second panel because he realises he can't understand a thing she's writing. Way to go, Lloyd! :B
Oh poor collette, but it's still funny, probobly because I could see it actually happening XD. Also in reply to your sig "Go back, back into a nebulas dream..."
