Ron's Patronus

[Shannon]

No: HPFGUIDX 109269

I was rereading OoP recently, and noticed something that struck me as a 
little bit odd.  During the last DA meeting, (US Edition, pages 606-607), 
they are working on producing Patronuses.  They mention Cho's swan, 
Hermione's otter, and she even mentions Lavender, Neville and Seamus.  But 
no Ron, whether he was having trouble or had done it successfully, 
nothing.  It seemed odd to me because usually when JKR gets into describing 
how students are handling difficult bits of  magic, she at leasts describes 
Harry, Ron and Hermione's efforts.

Anyone have any thoughts as to why he might have been left entirely out of 
this scene? Am I making something out of nothing?
