Just a bite for appetite

It´s only love, love, love!

 

LYSANDER
Demetrius, I'll avouch it to his head,
Made love to Nedar's daughter, Helena,
And won her soul; and she, sweet lady, dotes,
Devoutly dotes, dotes in idolatry,
Upon this spotted and inconstant man. (1.1.106)

 This is interesting.  Here, we learn that Demetrius was once engaged ("made love to") to another girl, Helena, before dropping her to be with Hermia.  Long before the fairies' love juice causes Demetrius to fall back in love with Helena (2.2; 3.2), we learn that lovers can be fickle and erratic, even without the help of some magic potion.
