oh control flow I don't understand you

app.js

// app.get('db') is a reference to my wrapper module over knex.js
// which just bundles actions/behavior into entity-named properties (tag, jobIndustries, etc.)

app.get('db').tag.getBelongingToJob(job.job_id)
.then(function(tags) {
	job.tags = tags;
	return app.get('db').jobIndustries.get(job.job_industry);
}).then(function(jobIndustry) {
	job.job_industry = jobIndustry;
	return app.get('db').jobCategories.get(job.job_category);
}).then(function(jobCategory) {
	job.job_category = jobCategory;
	return app.get('db').company.get(job.company_id);
}).then(function(company) {
	job.company = company;
	req.job = job;
	next();
});

var job = Promise.props({
    tags: pp.get('db').tag.getBelongingToJob(job.job_id),
    job_industry: app.get('db').jobIndustries.get(job.job_industry),
