More [ Winter Alchemist ] things. 

While Jade’s left leg got the worst of it, his left arm and hand weren’t spared, either. He has a full range of motion with the hand, more or less, but the nerve damage resulted in roughly half of it lacking any sensation (other than the occasional phantom pains).  The worst of it is on the outer edge, elbow to pinky finger.  In contrast, the inner side is mostly unscathed, and his thumb, index, and middle fingers retain feeling.   

It is unfortunate, but you won’t catch Jade complaining about it. At least he can walk.  Saphir wasn’t so lucky.
