We are given a flashback/dream sequence at the beginning of episode 2 of
_Attack on Titan_ , and there are a few references to the fact that time has
passed, but it doesn't look like much time has passed.

_Please note that the timeskip does **not** occur between Episode 1 and 2, but
**within** Episode 2._

The full story is revealed in **Season 3 Episode 6** and **Season 3 Episode
11**. Here is [a recap](https://attackontitan.fandom.com/wiki/Grisha_Yeager)
of what happened, starting from a scene in _Season 1 Episode 1_ :

> Upon learning from Mikasa that Eren wants to join the Survey Corps, Grisha
> is more obliging of the idea than Carla, asking his son why he wants to
> leave the Walls. Upon hearing his son's answer, Grisha announces that he
> will be departing, telling a bewildered Carla that there is no point in
> trying to stop an inquisitive mind like Eren's. Before he leaves, he
> promises to show Eren what he has been hiding in their basement when he
> returns.

>  Later, during Wall Maria's fall, Grisha travels to the Reiss Chapel in the
> night. Bursting in on the royal family, Grisha [...] begs Frieda Reiss to
> use her Founding Titan ability to save Shiganshina from the Titans that are
> breaking in, but she refuses. In desperation, Grisha activates his own Titan
> ability, easily beating Frieda in combat, and devouring her, before going on
> to slaughter the entire Reiss family with the exception [of] Rod Reiss, who
> escapes.

>  Traveling to Trost District, Grisha locates Keith Shadis and enlists his
> help in searching for his family among the refugees. Upon finding Eren, the
> two men learn that Carla has been devoured, devastated by the news. Telling
> Eren that he must avenge his mother, Grisha takes his son into the woods.
> When Keith tries to stop him, arguing that Grisha should not put such a
> burden on the boy's shoulders as he might not be gifted like Grisha, Grisha
> simply explains that the fact that Eren is his son makes him qualified, and
> orders Keith not to get involved.

>  In the forest, he entrusts Eren with the _key to his Basement_ and injects
> him with Titan serum, explaining to Eren that their memories will teach him
> how to use the ability. Transforming into a Pure Titan, Eren devours Grisha
> and returns to his human state, having gained the Founding Titan […].

And now, leading to **Season 1 Episode 2** ,
[this](https://attackontitan.fandom.com/wiki/Keith_Shadis) is what happens:

> Minutes pass when Keith unexpectedly hears thunder from the direction Grisha
> went with Eren, prompting him to venture into the forest to find them. He
> finds Eren lying unconscious with no sign of Grisha. He brings Eren _back to
> the shelter_ to rest with Mikasa and Armin.

In **Season 2 Episode 10** , during

> a conversation between Bertolt and Ymir, it is revealed that titan shifters
> _cannot_ remember whom they have eaten prior to their transformation.
> Furthermore, having been a pure titan herself, Ymir claims that _every day
> was like waking up into a nightmare._ That is why Eren thought his
> transformation was just a bad dream, when in fact, **it was not**.

On top of that, **Season 3 Episode 12** gives us a little insight on

> the _titan serum_ or _titan injection_ itself. It is believed to be made up
> of _titan spinal fluid_. However, the exact chemical composition remains
> **unknown**.

So now we see that the timeskip encompasses

> exactly _one night_.
