Hello where is the transcript for this video?

There is a question/answer set that may need attention, unless I'm really having a memory lapse!

The question is...

Which sentence reaffirms the fact that he does know about it:

The answer choices are...

En cuanto lo sepa.
Sí yo lo supiera.
Sí que lo sé.

...with "Sí que lo sé" being marked as correct.

Again, unless I'm really forgetting something here... I think either the question should be...
"Which sentence reaffirms the fact that you do know about it:"

...OR the correct answer should be:
Sí que lo sabe.

If I am forgetting something here, I will be happily corrected/reminded!

I selected 'por' as a possible correct word thinking it could mean "The train goes through Madrid"

Tomorrow by this time I will have been admitted to hospital  is translated as Mañana a estas horas habré ingresado en el hospital

I've also seen  "ayer fue ingresado en el hospital"  and "el médico lo ingresó en el hospital" so it seems to behave like a transitive verb.

Why then isn't it " habré sido ingresado" ?

Gracias

Hi, I am trying to understand this lesson, and am confused by the two examples shown.

 Why on the second example you   put (accidentally) but not on the first example?

A Juan se le olvidó traer el hielo.

Podemos usar yo de ti en vez de yo que tú aqui?  Intentó "yo de ti" pero estuvo marcado como error. ?Por qué?

Un amigo espanol me dejó que "La mujer con la que está hablando" es correctecto pero "La mujer con quien  está hablando" no es correcto. Puedes explicar la diferencia?
