Final answer:
There is no description of Leninia's actions upon seeing John at the lighthouse in the provided text excerpts, thus an accurate answer cannot be given.
Step-by-step explanation:
The scenario where Leninia acts after encountering John at the lighthouse seems to be absent from these provided text excerpts. Each passage offers distinct storylines and characters but none include a character named Leninia reacting to a John at a lighthouse.
Therefore, we cannot provide an accurate description or analysis of Leninia's behavior in that specific context without additional information or the correct source material. However, the extracts mention characters like Louisa, Kismine, and Mrs. Linde, suggesting varied narrative scenarios, none of which correspond to the question at hand.
