I find it strange how they both showed body parts in the same episode.
With Lewis F it felt like he became more cheeky (no pun intended) and alot more confident because LG has gone , but it was like he was flirting with Kay in a weird way . The way he announced it to both Kay & Zoe "right i'm getting naked now" knowing full well Kay would perv on him , and her reaction was that of a teen girl

. It was more like he was just more comfortable in his own skin literally than just showing off . But i think he knew what he was doing and he probably loves showing his body off .
Isaac showing his private bits was more of a "look at me look at me" arrogant narcissism all eyes on me ! . He thinks everyone wanted to see that and they shouldn't of encouraged him by congratulating him

, in his delusional head he probably thinks he's earned more "man points"

. does he think that makes him an alpha male just because people think he's got a huge one ?? clearly that's where his brain lives . I found him so sleazy ! .
