I think Rand and Mat's journey to Caemlyn in TEotW demonstrates their loyalty to each other and their friendship better than any other moment in the books. All that cuddling under hedges ... ;)
I also wanted to do a sketch that showed them early on in the series, just to highlight how far they've come from being just a couple farmboys traveling alone through the big, scary world, playing for their supper because they didn't have two coins to rub together.
Aw. They're so cute together.
