Now, it's time to bring it on home. The main turnaround for the tune is in measures 9-11. A VI7 chord (Ab7(13)) is used in measure 9 to prepare us for the V-I cadence in mms. 10-11. The tensions that work well on the Ab7 is 9, #11, and 13. In this case, we chose 13. The choices for the G7 chord is the same as for the C7 we used in measure 4. Our target chord (Cm7) is minor, so we can safely use b9 and b13 as tensions. Here, both are used.
For scales, the scale often used for a VI7 chord is the Lydian b7 (a mode of the melodic minor scale). The scale is Ab, Bb, C, D, Eb, F, Gb. For the melody in measure 9, we don't worry about that so much as playing a nice Ab7 arpeggio. For the G7, there are a number of scales that you borrow from (altered, diminished H-W). I just chose a hybrid that included the Eb, F, Ab, and B, since these contain the characteristic notes of the G7b9b13.
