Right Pull By;

Outsides Courtesy Turn and Veer Left as the Centers Step To A L-H Wave, Very Centers Left-face U-Turn Back (placing R-H on adjacent End's back), Courtesy Turn and As Couples Extend. EN: 20

Ends in Parallel R-H Two-Faced Lines. EN: 30

Notes:

The Courtesy Turn movement for the new Centers (after the R-H Pull By) is sometimes described as 1/4 Out; Courtesy Turn & 1/4 more. We dislike this definition for 2 reasons: EN: 50
The original Outside Belle's part is somewhat awkward because there is first a 1/4 Out (to the Right) and then Courtesy Turn (to the Left) 3/4, instead of just a smooth 180° Courtesy Turn. EN: 60
If you advance into C3, the caller may call a Left Chain The Square in which case we believe it is easier to remember to have the new Centers Step To A R-H Wave & then the Very Centers always turn the Ends. If, instead, you were to 1/4 Out, you can easily become confused as to who turns who. EN: 70

Hints:

After the new Centers Step To A Wave, it is always the Centers of the Wave that take the Ends back to where the Ends came from. EN: 80
