The Strudel Scene: There have been many interpretations of the scene in which Hans Landa begins to question Shoshanna, then eating a strudel. I will now break down the scene in detail being a detective myself and viewing the scene many times. Landa begins to question Shoshanna; who is very nervous by the look of her face and also stutters. The waiter then comes over and Landa requests two strudels, one for himself and one for Shoshanna. As for the drinks, he orders espresso for himself, and MILK for Shoshanna. Shoshanna face gets very tight and best believe Landa takes note of this as a detective as evidenced by him saying "no reason to feel anxious". The waiter then returns. Landa accepts the drinks but notices the strudel does not have cream on it(which is not kosher to jewish people and Shoshanna is Jewish). Landa, laughing, says to Shoshanna "Sorry I forgot to order the creme". Shoshanna, is quick to start eating the strudel(trying to finish it before the creme arrives) but Landa stops her; "wait for the creme." Landa, getting evermore suspicious as evidenced by his facial expression, then proceeds to ask Shoshanna another question. Right after this question is asked, the waiter returns yet again with the creme, interrupting the questioning process in which Landa wanted to see if Shoshanna could be quick to give an answer that made sense. The waiter proceeds to place the creme on both strudels. Landa, clearly upset at the timely return of the waiter, stares at the creme in a "that figures" type of manner, allows Shoshanna to take the first bite(once again, displays signs of discomfort breathing heavy and tightening her face), then proceeds to eat HIS strudel violently. Landa then re-asks his previous question, but Shoshanna already had time to think of an answer. Landa then lays it on heavy by asking question after question hastily after every response given by Shoshanna. Shoshanna gives answers back quickly. She answers how her aunt and uncle got killed during Blitzkrieg in which Landa replies; "Pity." After this, Landa continues to eat his strudel violently while cursing Shoshanna's lover, who is African American. Landa then proceeds to offer Shoshanna a cigarette. He does this to see if she smokes(which any girl who witnessed their parents murdered would surely need something like a cigarette to calm themselves). Landa, clearly suspicious, announces he has another question for Shoshanna. Landa then begins to stare deep into Shoshanna's eyes as if to say "Are you that one girl who got away?" Shoshanna, strong, smiles and waits for the question. Landa retracts and forcefully puts his cigarette out in the strudel, as punishment for the strudel interrupting the line of questioning earlier. Landa then walks out unsure.
In conclusion, Landa knew something was wrong with Shoshanna displaying many signs of discomfort. I believe Shoshanna was the only jew that managed to escape Landa. Landa is vexed by this. Shoshanna displayed her strength by answering quickly, not breaking under the pressure, and this is what Landa was and always is counting on as a detective. So it is my personal belief that Landa DID NOT KNOW WHO SHE EXACTLY WAS and accepted her story. He tried but Shoshanna would not bend under the pressure. Case closed.
