Benji (contains details from Monday's episode)

Not really a spoiler but thought I'd flag it as such in case anyone missed Monday's episode, we saw Benji debut and his involvement in Shireen's 'murder' was revealed

Did anyone find his comments to Nicola a bit weird when he said he missed her or something, and he gave her that creepy look which she didn't seem thrilled by? I wonder if they were a thing, or maybe she had him doing more than just killing/disposing of Shireen's body in the past?

Money would be a factor but it would surely take more than that for him to kill or cover up a murder for someone, so I wonder if they have more of a link than we know?
