Diana did not and had never considered Thor “dead weight”. Even during the time that he had been quite literally dead, she had never blamed him or thought he’d failed. In truth, she was more impressed with Thor than she had ever been, and she’d have been glad to tell him so, if he’d asked.
The Amazons had a tradition that Diana remembered well. It was most often used before battle, something of a war cry, though there had not been any battles while Diana was young. Hippolyta had seen to that. Still, Diana remembered the chills she had gotten as a very young girl, hearing her mother ask the Amazons to show her their fear, and hearing the Amazons tell her they had none... and mean it. A silly thing, perhaps, but not when one knew what an army of Amazons could do.
The point was, Diana had been raised with the understanding that cowardice was a greater failure than actual failure. And Thor, unlike most people, knew largely what Diana was capable of and how strong she actually was. Her brother had shown himself to be the more powerful of the two, and yet Thor had stepped forward anyway, and done his job. If he had not already owned Diana’s whole heart, he did now.
“I assume they would have,” she said softly, and she took the hand he’d used to pat hers, lacing their fingers and leaning against his shoulder. “This place is so very confusing.” Diana had leaned against Thor’s side, and that left her close enough to press a kiss to his cheek.
