Harry views Jake as her closest comrade. One of few people she can say she trusts with her life, the two lived together rough and took care of one another in their darkest times. The two don't share any romantic feelings, but would live their whole lives together, bickering like an old married couple if they could.
Jake looks up to Harry and her strength, and finds her extremely reliable. He goes out of his way to keep her safe and secure, also finding her close to one of the only people on earth he could say he truly trusts with his life. He had perhaps a fleeting crush on her once, but would rather just be by her side as a close pal instead.
Teddy, due to his Amnesia, initially has forgotten about Arthur.
When reunited and told of him, he finds his little brother adorable - having had similar feelings prior to forgetting him. Despite Arthur's grumpiness he is convinced Arthur has a 'soft side' and his snide remarks hardly affect Teddy.
As a result of this big-brotherly-love and trust, he is deeply hurt when he learns of Arthur's actions, which is also what caused the amnesia to begin with: the shock his brother would do such a thing to him.
Arthur, largely, feels indifferent about Teddy - however that is only surface-wise.
Underneath his cool and uncaring outer shell; he greatly resents his brother, finding his endless enthusiasm nothing but a nuisance and hating him for being the 'main focus' as both older brother and title inheritance.
This anger was enough to attack Teddy, finding sick thrill out of it to the point he would attempt to harm others with intent to replicate the same injuries.. but they're never enough.
