"I love Thea and all, she is wonderful to be around but.... she needs to grow up. It may seem blunt and harsh, but it is the truth. She needs to grow up. She needs to learn to reign in those emotions, because that alone is going to get her into trouble. Hell she would be terrible at gathering information, just because of the emotional factor. She would give too much away with just that." Natalia pointed out after a moment in time. In no way was she intending to be rude, she was just pointing out her personal opinion, which he could agree or disgaree with. When it came to gathering information from people face to face, Natalia was bad at it herself and she knew it. This is why she left that stuff mostly to Daenerys, who could get about anything out of anyone.
