Does this mean it sends a query every time they see an NPC, even if they've seen it before?

I am trying to understand how the server and client interact with quests and NPC's in general. For instance, where does the server send the NPC data of those in range of the player? I am not sure how the client tells if it has a quest or not. Does the NPC data simply come with Yes/No it has a quest? Then the client just queries the server for the quests of a certain NPC? However I only see an opcode for the server to send the list (SMSG_QUESTGIVER_QUEST_LIST) no client opcode for requesting. In any case I think there are a lot of ways it could be done, just not sure how it is done here. Can anyone give me a brief description on how the client and server do quests?

Bear with me here as I am new to this and trying to understand the chat system. This is more about the client and server interaction. I noticed that the game sends the GUID to the client for messages. I was wondering how the server is to get the name of the sender if the client has not interacted with that player before? I noticed there is a name query so I imagined it sends this. Seems like a ton of requests if many players are all talking at once in global channels. If this is the case, does it just store the message until it receives a query response? Or am I completely wrong in how this works? Any information is appreciated.
