Iodine clock reaction

If the thiosulfate ion solution was omitted what would appear in the solution?

I know that once the thiosulfate ion is responsible and exhaubated the reaction rate stops and iodine is presented in the color blue.
In that case, if thiosulfate ion solution is omitted the solution (reaction rate would continue) would not present iodine(?).

If the thiosulfate ion solution is omitted in the iodine clock reaction, the thiosulfate ions will no longer be available to react with the iodine that is formed during the reaction. The reaction between iodine and thiosulfate ions is responsible for consuming the iodine and preventing it from being visible in the solution.

Therefore, if the thiosulfate ion solution is omitted, the iodine that is formed during the reaction will not be consumed and will remain in the solution. As a result, the solution will turn blue due to the presence of the unreacted iodine. This color change is a characteristic of iodine in the solution and confirms that the thiosulfate ions are indeed necessary to prevent the appearance of iodine in the reaction.

not blue black color would appear and it would slow down measurement
