i like to call back to old art, is old and not the best but it's a part of the story

anyways this is the first time Thomas transforms and it was painful that it woke up his dad.

of course his dad is upset and scared even to the point of crying but still tries to help his son

but Thomas yell woke up other ponies and of course the town will wake up too because of the commotion and some ponies were ready to kill Thomas once he transformed because they know he's transforming into a wolfpony but did not do anything at first because they want to be sure

Thomas and his dad tried to run but Thomas was captured yet his dad save him and told him to run away he did and the pants like a dog and fell asleep, don't worry no one got him

so ya it seems like a nightmare for Thomas but is real it's really sad for him

there is not much to say anymore about this what happened afterwards will be shown next time
