Grand purpose? Roman couldn't exactly disagree but his intentions were quite so... selfless, he guarded the bridge to take care of the people he cared about and that was it. He didn't do it because it was the right thing to do he did it because he was confident that if he was on the bridge then the chances of something or somebody getting through that could be a risk to Summerview would be slim at best.
He remained steadfastly where he was as the Fae wandered off after leaving the invite to join her for a picnic hanging in the now empty space between them. Hm, interesting.
Roman chanced a look over his shoulder in the direction of the bridge as he gauged how comfortable he would be to leave his partner alone for a little while longer. He decided that a little more time wouldn't exactly kill him and then strolled after her as she looked for a spot to make a picnic.
