If you want to funny about you could argue 35A/35C however these don't represent the initial reason behind why use 2A/2C. As pointed out above it was supposed to be for anti clockwise and clockwise loop however silver arrows don't do a loop anymore and GNE have bother other services lettered like this expect the Laser Services which use the 'C' as way of identify the evening route to South Hetton. 36A/36C used to be part of this, however even these the 36 service don't use this lettering any more.
Yes does do a Loop from Fatfield heading towards The Galleries - 2C for example - via Harraton and Lambton to The Galleries, Then turns into a 2A and goes via Biddick and Fallowfield Way back to Fatfield, So therefore they a Clockwise/Anti Clockwise Loop of Washington, also as Mentioned Previously the 2A goes via Barnwell to Penshaw whereas the 2C goes via Shiney Row. As for the Lasers, that would be because the 35/35B finish at Low Moorsley, The 35A finishes at Rainton Bridge and the 35C finishes in South Hetton, Also the 35/35B and 35C go via Royal Hospital whereas the 35A goes straight through to Silksworth via Barnes Park, Not really hard to Understand why there Numbered A/B and C is it to be honest.
