The group of explorers didn't encounter any problems on their return journey. Toz taught Charlie a bunch of things when it came to cooking. Amanda and Din hunted fresh beasts and animals the other two could cook. Toz would have assisted, but he was still recovering, so the others convinced him to rest properly. The cats slept and relaxed in Toz's familiar space most of the time, occasionally coming out to eat.
Even if they were practically rushing back toward Yellow Spark, even if they ran, it would take several days. During evenings after they set up camp every night, they found themselves with a bit of free time.
Charlie took the time to revise what Toz had taught him while Amanda and Toz sparred with Din watching them. When the three had saved Toz, they had noticed him holding a sword, and Amanda, as a sword-wielder herself, wanted to spar with him once he was strong enough.
