LOL!
Marcus has openly confronted Lisa. The reason he argues with Sree all the time is because unsurprisingly, he's the only one who really gets under Marcus' skin.
Sree would brick it and run a mile from Marcus if they were on their own in the street having an argument.
Not that I think Marcus would actually have any violent intention towards Sree, but Sree's such a little rat he'd run anyway or harrass a stranger and try to tell them he's being bullied or attacked or something...
