Notes:

Explode The Line is the generalization of Explode The Wave [Plus]. EN: 60
The most important thing to remember about Explode The Line is "Centers Step Forward". EN: 90
If an End and adjacent Center are facing the same direction, the End should back up slightly before turning 1/4. Dancing Explode this way is preferable because, upon completion of the call, the Couples are not offset and no adjustment is required. EN: 100
Be sure to adjust to Facing Couples before the Right Pull By. Should you fail to do this, you may end offset after the Pull By. The ending formation should be Back-to-Back Couples. EN: 110
After Explode, everyone can Roll. After Explode The Line, nobody can Roll. EN: 120
