<thinking>Let's approach this step-by-step:
Time to work through this systematically (CoT):

Step 1: What is the challenge asking me to do?
Identify the number of character "t" in the expression "Tortuous"

Step 2: Deconstruct the word.
T-O-R-T-U-O-U-S


1. T
2. O
3. R
4. T
5. U
6. O
7. U
8. S

Step 3: Determine the positions of the letter "t".
The letter "t" appears at the 1st, 4th positions in the word.

Step 4: Enumerate the letters.
R: 1, T: 2, U: 2, S: 1, O: 2

Step 5: Inspect the letters we quantified.
The specified letter was "t" and there we found 2 overall.</thinking>
