Was I the only one who found it funny that Jason is one of the youngest amongst the seven? Percy, Annabeth, Piper and Frank are all older than him and obviously Hazel is the youngest and not too sure about Leo. Percy and Annabeth are almost 17, Frank was 16 already in SoN and Piper's dad told her in TLH that he would have bought her a car anyway since she turned 16 in just a couple of months so she's also 16 by now.

I just kind of feel like someone should tease him about this haha xD.
