This is weird

During my previous module, a bloke started the class towards the end of the year, despite the lecturer saying it was too late in the day. He didn't do any homework or crits etc and never said a word.

He joined the current module in lesson 4. Once again, he doesn't participate or do any of the work and the lecturernever asks him to take park. Frankly, we're all finding it a bit odd and think it's dodgy.

What do you all think?
