Here's a breakdown of what Holmes meant:
* "I never get your limits, Watson": This implies that Holmes sees Watson as having a vast capacity for growth and development, which he constantly underestimates.
* "There are unexplored possibilities about you": This statement highlights Holmes' belief that Watson possesses untapped abilities and talents, which he himself has not fully recognized.
In the story, Watson exhibits surprising resourcefulness and bravery in confronting the supposed vampire. He takes initiative, makes insightful deductions, and even displays a willingness to take risks. This unexpected behavior impressed Holmes, who had always seen Watson as a loyal friend but perhaps not as sharp or courageous as he truly is.
By saying these words, Holmes acknowledges that he has misjudged Watson's capabilities. He sees him not just as his sidekick or chronicler, but as an individual with potential that extends beyond the limits he had previously perceived. This is a testament to Holmes' ability to recognize talent in others, even if it is hidden or underestimated.
