Fergus' Stable helped Paxton survive the most difficult period of his life. Now, due to his health problems, the stable is in a difficult situation.
They were only halfway through the season. Steve won't be back on track anymore, so someone else has to take his place. Who? It was the middle of the season, off-transfer period, they won't find anyone fast enough and Fergus' Stables will suffer losses.
Martin was the only solution and he was the right solution, he just had to focus on the race ahead, not on the fear that his lover's and idol's professional career was over. Martin was supposed to focus on winning, not pity.
The world hasn't collapsed yet. Shortly after hearing the doctor's judgment, Steve felt as if everything had just started to collapse, but it wasn't like that yet. Not yet. Five percent of the odds is so little, but always more than if he hadn't had a chance, and talking to Karl helped him visualize it.
