regarding sequel story ideas and thoughts Part 2
Night terrors are always a good PTSD symptom, showing how the rest of the teams deals with/helps Claw. I see Marshall as being the most helpful because he gets it, Chase being supportive but coming across as slightly condescending, Skye as caring but to the point of Claw feeling like she is being patronizing, Rubble as confused and worried, Rocky as supportive, Zuma as supportive but not quite taking it seriously. Since they'll be back in Adventure Bay, adding Everest in makes sense and maybe Tracker too; they would be supportive but excessively worried/nervous and confused respectively.
Another idea might be that Claw accidently hurts people/pups who startle him, has flashbacks while awake at time that cause him to do dangerous things, like run away from the Duke or Archeos across a busy street and either get hurt or almost get hurt, lashing out with hurtful words when other try and help him (possibly to the point of challenging them to duels, maybe he wins some and loses others before Marshall finds out and shoots him with a sedative dart)
