Mobile Article Context Object

Is there a way to get the currently rendering message from a mobile blog article page? (ie. ${env.context.message.id}) I can't seem to get any type of env.context.message calls for the message itself or author variables to work.

Ones I've tried:

${page.context.thread.topicMessage}

${env.context.message.uniqueId}

<#assign author= env.context.message.author />
${author.id}

Thanks,

Jason
