Currently there is no way to edit the original message being forwarded or replied to on Verse for Android. This makes it impossible to do things like insert your comments within the original message or correct information or omit information before forwarding. What's more, you can't even copy text from a message and paste it in a new message. (I will also post that as a separate idea/bug). It should be possible to edit the message being forwarded/replied just like can be done in the Notes client.
