Где встречаемся? Без понятия. Так и знал.

Russian often drops subject pronouns when the verb ending already shows who the subject is.

Встречаемся has the -ем(ся) ending, which tells you it is we. So:

• Где встречаемся? = Where are we meeting?
• Мы где встречаемся? is possible, but мы is usually unnecessary unless you want emphasis or contrast.

The same thing happens in Так и знал: the я is omitted because it is understood from context.

The verb here is встречаться, not just встречать.

This matters because:

• встречать usually means to meet/greet someone, to pick someone up, or to encounter
• встречаться often means to meet each other, to get together, or to arrange to meet

So in this sentence, встречаемся has a reciprocal sense: Where are we meeting each other?

Compare:

• Я встречаю друга на вокзале. = I’m meeting/picking up a friend at the station.
• Мы встречаемся у метро. = We’re meeting by the metro.

Russian often uses the present tense to talk about planned future actions, especially in everyday conversation.

So Где встречаемся? literally looks like Where are we meeting?, but it can mean:

• Where are we meeting?
• Where shall we meet?
• Where do we meet? in the sense of a planned arrangement

This is very natural in Russian.

A related option is Где встретимся?, which uses the perfective future and can sound a bit more like Where shall we meet? / Where will we meet? Both are common, but Где встречаемся? feels very conversational.

Both can be translated similarly, but they are not exactly the same in feel.

• Где встречаемся? uses the imperfective present and often sounds like talking about an arranged or ongoing plan.
• Где встретимся? uses the perfective future and focuses more on the single completed meeting event.

In casual speech, both are natural. Very roughly:

• Где встречаемся? = So, where are we meeting?
• Где встретимся? = Where shall we meet?

The difference is usually small in practice.

Без понятия is a fixed colloquial expression meaning No idea or I have no idea.

The word без requires the genitive case, so:

• dictionary form: понятие
• after без: понятия

Literally, it is something like without any notion/idea, but in real use it simply means no idea.

This is an idiomatic phrase, so it is best learned as a whole expression.

Yes, Без понятия is conversational and common in speech.

Other natural ways to say I have no idea include:

• Понятия не имею. = I have no idea.
• Не знаю. = I don’t know.
• Я не в курсе. = I’m not informed / I don’t know about that.
• Без малейшего понятия. = No idea whatsoever.

Among these:

• Не знаю is the most neutral and basic
• Понятия не имею and Без понятия are very common colloquial choices
• Без понятия is short and punchy

Так и знал is an idiomatic expression meaning something like:

• I knew it.
• I thought so.
• Just as I expected.

The combination так и adds the sense of exactly like that, just so, or as expected.

So the feeling is not just I knew, but more like:

• I knew it would turn out this way
• I knew that was going to happen
• Yep, exactly as I thought

It is a very common Russian reaction when something disappointing, predictable, or unsurprising happens.

Because Russian uses the past tense in this expression the same way English does in I knew it.

The idea is: I already knew / I had expected this before this moment, and now events proved me right.

So even though the speaker is reacting now, the verb is past because it refers to an earlier state of knowing or expecting.

This is completely natural Russian.

Again, Russian often omits subject pronouns when they are obvious.

The full sentence would be:

• Я так и знал.

But in conversation, я is often dropped:

• Так и знал.

This sounds very natural and conversational. The speaker is still clearly I, just understood from context.

Yes, very much so. It sounds short, conversational, and realistic.

• Где встречаемся? = casual planning
• Без понятия. = brief, informal answer
• Так и знал. = natural reaction

Russian conversation often leaves out pronouns and other words that English would include, especially in short exchanges like this. That is one reason the dialogue feels compact and direct.

Yes. In spoken Russian, short fragments like this are very common.

Even though it is not a full sentence in the strict grammatical sense, it works perfectly as a complete response in conversation:

• Когда он придёт? — Без понятия.
• Куда идём? — Без понятия.

English does the same thing with No idea.

So learners should not expect every Russian reply to have a full subject and verb. In real speech, short answers like this are extremely common.
