A/N: Again no specific episode, though it would have to be after Dead Reckoning (mind you, it would be anyway since Robbie's in it) :)

Impulsive

It was no secret that Robbie Ross was impulsive. He acted on his instincts, which often led him to get into trouble, particularly with Michael.

Sometimes Robbie suspected that Michael had never had a rash impulse in his life, but then he would look at the relationship he had with Jackie and he would think again.

Robbie often found himself at a loss to explain the relationship between his conservative boss and mischievous colleague. He knew that they had been friends for many years and he also knew that if Michael were ever to make a rash decision it would be in regards to Jackie.

He'd heard a story once from Stuart about how Michael had jumped off a cliff in order to save Jackie. An impulsive move if he ever heard one.

He'd also seen firsthand how Michael would manoeuvre himself to be between Jackie and danger. Often, Robbie noted, without even thinking, just acting instinctively.

Not that he could blame him; he felt a certain attraction for Jackie himself and enjoyed the playful banter they often indulged in. But he also noted that her banter with Michael often had a more serious edge to it, tinged by real affection not just play.

It was in those moments that he was a little jealous of Michael, jealous of his easy familiarity with Jackie. Even though he knew their relationship was primarily based on the trust and loyalty that had developed between them over the many years they had known each other.

Because they had worked together for so long their relationship was something that you would expect, but there it was an instinctual nature to it that made it special. Like their relationship was an integral part of the two of them.

Jackie didn't defend Michael because he was her friend, or even her boss, she defended him because it was some innate instinct. Likewise, Michael didn't trust Jackie simply because he had worked with her so long, he trusted her on impulse, simply because she was Jackie.

Robbie had no qualms with coming up with his own conjectures as to why that was. He was enough of a player to see the underlying attraction between them and enough of a gentleman to know that it was sincere.

Their relationship was many things, most them inexplicable; unless you realised that it was so much a part of them that it had become engrained in them both. Similar to an instinct or an impulse that they didn't question, just obeyed.

What Robbie couldn't figure out was why they didn't just follow the impulse to its logical conclusion.

A/N: I see Robbie as probably having the best insight into their relationship, probably because he's more their contemporary than the others were.
