Though Hanna and Caleb's kiss last episode affected Spencer and Caleb's relationship, Spencer will be dealing it with ways she may regret in the future. In addition, Mona will be intervening with the cover up plan the PLLs will be trying to put up, according to Pretty Little Liars

The last episode showed how the PLLs were really worried about their friend, Alison, who was in the hands of her husband, Elliot Rollins. Allison tried to escape the hospital by strangling Rollins with an IV tube but she was still overpowered by her husband, her being strapped down back to bed after being injected with a sedative.

When Spencer learned about Caleb and Hanna's kiss, she did not put up any effort in talking again with Caleb, although the latter tried to win her back. As for Toby, his engagement went on with Yvonne despite the seemingly burning out flames of their romance.
