Trap Master can only be flipped during your turn or by the effect of another card. Since no card has been activated to trigger such an effect, Trap Master cannot be activated in response to Trap Stun.
THE DOG GOES.
The effect of Prediction Princess Tarotrei can flip trap monster face up on the opponents turn.
THE DOG STAYS
Once we send that Prediction Princess Tarotrei to the graveyard, our trap sealing will stick around.
The dog goes.
Ritual Sealing does not negate, only destroy. Prediction Princess Tarotrei is destroyed, but its effect is still carried out.
