Finishing out the body, cuts are made down through the pelvis to loop around the upper hip, effectively isolating it from the edges and verts of the pelvis so the legs can be animated without inadvertently affecting the pelvis.
Edges are of course cleaned up to get rid of Tris, but you get the idea. Skipping ahead, the edges that make up the knee cap are just deleted entirely to save time, redrawn, then reconnected.
And the smooth preview
