Totally I edited it to say that first.

Also, it feels like that guy is defensive and feeling butthurt. So op can try pretend he's awesome and give him all the difficult tasks to prove. If he fails you know what to do. If he is good then less work for you.

As the lead you don't need to be always the rockstar, the coolest managers are the ones create chance for teammates to be rockstars.

(I had bad leads where it just felt like what is the point for me existing here as a code monkey if this guy sorted it all. Tho I would never sabotage it. I just quit;))
