Ron was right in suspecting that Harry had his own sucpicions about what was between his two best friends, but they were tame in comparison to the truth. He had not been aware that Ron had intended to ask Hermione to marry him. For some reason, he simply hadn't put two and two together, which he supposed wasn't really that surprising. He often had trouble with that.
When Ron admitted how far he had come in regards to Hermione, Harry's eyebrow raised, but his shoulders slumped just slightly. So he was in love with Hermione, but marrying Ana. That could prove to be more difficult then he was expecting. "Sorry to hear that, mate." he responded, it being the only thing he could really offer. He wasn't the one with the good advice. That had always been Hermione and he didn't think it would help coming from that direction this time.
"What are we going to tell your Mother?" he asked, a sudden thought coming to him and a certan article popping into his head. Mrs. Weasley hadn't taken it lightly when she thought Hermione had hurt him, he didn't want to think what would happen if she thought Hermione had hurt her actual son. "I mean, in regards to Hermione not being at the wedding? For the most part, we're always together. I'm sure she'll think it a bit suspicious."
