I think by now, Hanna/Caleb are my favorite OTP in this show.
I loved it when Hanna took Caleb away when she thought the cops were tracking him and tried to protect him. She is terrified he is going to run (her family situation has given her understandable abandonment issues) and I loved it when he told her he wouldn't, because that is what she needs to hear so badly. And she tells him she will run with him. Woobies! She really needs someone like Caleb, someone who will stay for her, and he really needs someone like her, someone who protects him and cares for him and loves him, to whom he can belong.
The coda to this episode was both lyrical and heartbreaking - Caleb and Hanna sitting there, watching a perfect family from outside in, both deprived of it in different ways and longing and angry and lost, but still together.
