Quicks was very brave for running into the middle of the stampede to save Speckles from being crushed, I got so sad when he died and also when a dinosaur accidentally kicked his jaw while running. RIP Quicks.
Theory: what if Quicks survived the stampede after he got Hit by dinosaurs and when he wake up he didn't find his mother or his siblings and he heard one eye's roar knowing that one eye killed his whole family not knowing his little brother speckles survived.he abandon his home that is now one eye's territory. Quicks after a long travel he find a new land that he can call it home, hopefully there will be a therd movie of speckles the tarbosaurus when junior meet hes long lost uncle.
I adore Quicks the Tarbosaurus, he’s very impressive and I feel sad for him because he sacrificed his life for saving Speckles which seems very sad. Quicks is a better Brother than Scowler, Kron and Buck the Apatosaurus in my opinion. Quicks may be gone but his legacy looks lives on along with the other Tarbosaurus in the franchise.
