After several kisses Emily had fixed Ollie with a look and told him flat out that he was not allowed to be mean to Mal. He made Kat happy and that is all that matters. Also she promised him that if he did anything to him or threatened him in anyway that greeting kiss was all he was going to get from her on this trip. No sexy fun times.
She had wanted to discuss with him the prospect of him turning her in the future but another time. Maybe at the spring formal. She had time.
Emily came back inside the house her hands wrapped around one of Ollie's as she dragged him inside. She gave a smile to Kat and nodded. And for good measure as she didn't think she'd done it yet she went over to Mal and leaned down to whisper in his ear,
"Just to let you know if you do ever hurt her I will go Liam Nesson from Taken on your ass, you get?" She only said Ollie wouldn't threaten him...she never promised she wouldn't. She was pretty sure that he wouldn't but Kat was practically her kid sister an she wouldn't be a good big sister if she didn't warn the boyfriend of potential bodily harm if he stepped out of line.
