Could this be it?

A shock announcement came from the Love Island camp yesterday with the news that Niall Aslam had left the villa and now viewers think they've worked out the reason why. Hardcore fans have been sharing their thoughts on Twitter and while it's probably just the usual speculation that occurs when a contestant exits a reality show without warning, fans are intrigued nonetheless. They think it's to do with the dramatic showdown between Rosie and Adam which dominated last night's episode. If you were watching, you may have heard Rosie say that Niall hadn't been honest with her and she believed Adam was now doing the same thing. Rosie said:

"You say about Niall not being honest the other night, but you literally did what he did..."

Of course, people were quick to jump on this angle and went straight to Twitter to share their musings. Note there's a specific account dedicated to the mystery of why Niall left, that's dedication for you.

And if he can't return to the villa either then where did he go. I'm just really confused at the moment. Upset and confused. Did something happen between him and Adam or him and Rosie. Or did Georgia do something. Did he break the rules in the villa? Did he commit a crime?? ??

Looks like he broke the rules, Adam and Rosie refer to ‘lying like Niall’ in the midst of their argument

Why did Rosie say “you say about Niall not being honest the other night” when she was having her showdown with Adam? I’m so confused #LoveIsland

A lot of people think Niall may have broken the rules in the villa but either way, we'll probably have to wait a while to find out.

Did anyone else notice Rosie reference Niall’s dishonesty in her confrontation with Adam, I reckon he’s broke the rules in some way and that’s why it’s so hush hush #LoveIsland

It might just be that Love Island life wasn't for him and so he decided to leave, we'll just have to wait and see what other drama unfolds...
