Personally, it's about unreciprocated love, or circumstances that are unfair for one party.

No matter how much they wish to validate the situation, the other person cannot cooperate. It's simply not true for them.

'In Context She said, these terminals once again These wasp's nests, these terminals once again These heart swells, these contexts in your head'

The desired circumstances are the 'context' which is referred to. 'Terminals' are just points, like airport terminals; sendoff locations, or 'terminals' in the brain that relay messages.

In reference to the latter, she's talking about his brain signals and how they're being activated by the desires, by the want or longing to make the 'context' true. 'Wasps nests' are the stings or the pain inflicted by these constant desires that end up nowhere, with no results. 'Hearts swelling' are his feelings growing and growing, but with nowhere to belong, because they cannot be accepted. 'In context' is her approaching the present situation, where he is longing for 'contexts' in his head. They allude to the same thing, but exist in different planes to contrast it. In context is realistic and contexts in your head are idealistic.

'Oh hell no, these vessels Our heart swells up, these vessels Our heart swells up, which makes us explode'

Vessels -both in the brain and in the heart. Brain vessels, thinking too much of the situation. Excessive contemplation and desire. So much that the heart vessels 'swell' for what they long for. Both of them together eventually prove to be too much and 'explode'.

'We could set it on fire for them'

That's his wishful thinking again. 'Set it on fire' is the start of a relationship. 'Fire' also alludes to how passionate it could've been or how much the desire burns and longs for it to be so that it's a 'fire', which eventually leads to the 'explosion'.

Just a personal interpretation. :]
