How do I group separate emails into the one conversation if they weren't already?
For instance, I email X, the manager at a client, asking something. Then Z, her secretary, replies with the answer. Is there a way to group these emails into a single conversation?
I don't want to use labels, I really want to group the messages.

Forward one of the e-mails to yourself using the subject line from one of the other e-mails.
Unfortunately, that seems to be the only way, and the e-mails you forward won't be clearly indicated as having been sent by the real sender (nice header with their name in colour), but it will work to get everything in one place.
Given these two e-mails, like in your scenario:
E-mail 1:
E-mail 2:
...to get everything into one conversation, you send this e-mail:
E-mail 3 (a forward of Person 2's message, with the subject manually changed):
(I am saying "forward" instead of "reply" here in order to bring any attachments into the conversation too!)
