Just wanted a lens combination suggestion from you experts

I have a Canon 24-70mm f2.8 L lens already. What I was wondering is, what should I get next? I think now that I have a good mid range zoom, I would like to get a fast prime. I like low light photography so a low figured aperture is a must but I having some reach with a telephoto would be great too. IQ is first and foremost, the quality that I value the most in this case however. The lenses I am thinking about are:
1. Canon 35mm f1.4 L
2. Canon 135mm f2.0 L
Any suggestions welcome.
