In my opinion I think that Utterson is doing the wrong thing in trying to protect his friend because as this was based in the Victorian times it shows that a true Victorian gentleman would be a loyal and honest man, here Utterson is a lawyer, even upon discovering Hyde's letter is almost certainly a forgery, Utterson refrains from confronting Jekyll to protect his reputation, In this way, Utterson loyally protects his friend. In contrast, Jekyll lies to Utterson, defending Hyde with a fake letter. Here, for the first time, the reader begins to see hypocrisy in Dr. Jekyll. He claims to be a loyal and honest man, but in fact he is a liar and forger.

I think the correct word would be meanwhile because the second point is something unrelated to the first point, but the two points are happening at the same time. all the other words in fact, obviously, and besides are used when the point relates to the previous point. hope this helps!
