Gamora is surprised by how well this is going. She expected them to make complete fools of themselves and the Guardians in general. Evidently, their interests overlap in several places. She watches at how 'Cap' seems to actually listen to Drax and value what he has to say. Rocket seems happy that someone is able to actually follow what he's saying fully.

She lets herself relax a little. They made the right decision coming here. "Nebula will still be difficult, but if they can get along with these two we should have nothing to worry about." She whispers back. Needless to say she will wish later she asked more about Steve's enhancements because he is definitely listening in.
