Tell them the mission

'My mission is to sneak into the Doom Castle located at the center of the capital of Latveria' said Natasha, explaining the first part of her mission to Emily. 'But unfortunately, due to unknown reason my jet was locked by some kind of air defense system that appears from nowhere...' said Natasha.
'Oh, so that is why you said your plane crashed' said Emily, 'Why do you want to go there? the people of Latveria have lost their soul to worship a false self-called king, there's nothing there but tyranny.' said Emily sarcastically.
'My main objective is to find Dr.Doom and retrieve some intel about his current interest. Dr. Doom and Latveria are considered hostile to the world. It is necessary for us to keep an eye on him. Also, our intel tells us that Dr. Doom is keeping a low profile at this time, which benefits me to sneak in unnoticed' said Natasha.

When hearing the name of Dr. Doom and the plan, Henry and Mike that stand near the table burst into laugh same as Emily with a peal of small laughter on her face. 'What are you laughing at? Did I say something funny?' said Natasha.

'Yes, What you said is really funny, Miss Romanoff.' replies Henry, 'I get why you are shot down from the sky, HAHAHAHA...' said Mike laughing loudly.
'What's wrong with what I said?' asked Natasha unable to digest their reaction.
'Okay, Zip it' demands Emily to silent the laughter around the house. She turned to Natasha and said 'The intel you rely on is wrong and you are really lucky that you are still alive right now, also the plan of yours won't, I guarantee that.'

So many questions flow into Natasha's mind. The intel is from the state of art SHIELD intelligent network, how did it go wrong? And what's wrong with my plan?
