Lochinvar offered to dance with Ellen so that (D.) he could see Ellen again and have a chance with her, which ends up affecting the outcome of the poem "Lochinvar".
"Lochinvar" is a poem written by Sir Walter Scott. The poem focuses on young Lochinvar, a gallant knight that is in love with Ellen, who has been forced to marry someone else. Lochinvar does not have a good relationship with her father since he was the one that prohibited Ellen to marry him. When Lochinvar enters the bridal hall, he starts to dance with Ellen. During the dance, he explains to her that there is a horse waiting for the two of them outside and that this is their chance to fly away from her family and her new husband. After Lochinvar reveals this, both of them run to the door and escape in the horse. In that way, Lochinvar asks to dance with Ellen in order to see her and talk to her about his plan to run away together.
