“Rising” is episode thirteen of season one of Dark Angel.
At the end of the previous episode, “Art Attack”, Logan felt pain when he hit is foot on something. Given that he is paralysed from the waist down from being shot, that shouldn’t be possible. He’s gone to see a doctor, but the doctor says that nerves don’t get better (even though his apparently have); however, his blood has unusual properties.
In “Out” Max transfused some of her blood into Logan, and it looks like that may be healing him. So they give him some more to see what happens.
The South African supersoldiers from “Red” have returned and they still want Max’s DNA, and in a straight up fight Max will probably lose; there are more of them than there are of her, and several supersoldiers tends to beat one supersoldier.
