Based on the provided story, here is the assessment of the Tragedy Degree and Comedy Degree:

**Tragedy Degree:**
- While the story involves some elements of mystery and moments of suspense, there are no significant tragic events, losses, or profound emotional setbacks.
- The overall tone is one of discovery and realization rather than tragedy.

**Comedy Degree:**
- The story does not center around comedic plots, nor does it conclude with an especially happy or humorous ending.
- It is light-hearted to an extent, with some moments of warmth and camaraderie, but it lacks substantial comedic elements.

Given these observations, here are the scores:

```json
{
  "TragedyDegree": 2,
  "ComedyDegree": 3
}
```

### Justification:
- **Tragedy Degree: 2**: The score is close to the minimum because the story contains almost no tragic elements. It is largely an adventure and mystery tale with positive outcomes.
- **Comedy Degree: 3**: The slight comedic degree comes from the warm interactions, particularly with Thaddeus, but the story lacks explicit comedic content and situations. It also does not culminate in a highly emotionally delightful ending but rather an intellectually satisfying one.
