Dímelo de verdad: ¿te gustó más ese personaje o el villano del final?

Because it is an affirmative command with object pronouns attached to the end.

• di = say / tell
• me = to me
• lo = it

So Dímelo literally breaks down as:

• di
  • me
    • lo = tell it to me

In Spanish, affirmative commands attach pronouns:

• Di = Tell
• Dime = Tell me
• Dímelo = Tell it to me

This is completely normal Spanish word formation.

The accent mark keeps the stress in the right place.

Without the accent, Spanish spelling rules would make the stress fall naturally on the second-to-last syllable: di-ME-lo. But the correct pronunciation is DÍ-me-lo.

So the written accent in Dímelo is there to preserve the original stress when pronouns are added to the command.

This happens a lot with commands plus pronouns:

• da → dámelo
• cuenta → cuéntame
• explica → explícaselo

Here de verdad means something like:

• honestly
• for real
• seriously
• truthfully

So Dímelo de verdad is not just tell me it in a neutral way. It adds the idea of be honest with me or tell me seriously.

It is a very common everyday phrase in Spanish.

For example:

• ¿De verdad? = Really?
• Te lo digo de verdad = I’m telling you honestly / I really mean it

Because gustar does not work like English to like.

In Spanish, gustar works more like to be pleasing to someone.

So:

• te = to you
• gustó = was pleasing
• ese personaje = that character

So te gustó ese personaje literally means:

• That character was pleasing to you

That is why Spanish uses an indirect object pronoun like me, te, le, nos, os, les with gustar.

Examples:

• Me gustó = I liked it
• Te gustó = You liked it
• Nos gustó = We liked it

Because each option being compared is singular.

The sentence compares:

• ese personaje = singular
• el villano del final = singular

So Spanish uses singular gustó.

If the thing liked were plural, you would use gustaron:

• Me gustaron los personajes = I liked the characters

In your sentence, the structure is basically:

• Did that character please you more, or did the villain at the end please you more?

Since each option is singular, gustó is correct.

Because the speaker is asking about a reaction to something already experienced, such as a film, series, book, or game.

• ¿Te gustó...? = Did you like...?

This is the preterite, used for a completed event or finished experience.

If the speaker were asking more generally or in the present, you might hear:

• ¿Te gusta más ese personaje o el villano del final?
  = Do you like that character more, or the villain at the end?

So:

• te gustó = past reaction to something completed
• te gusta = present/general opinion

Más means more, and here it is used for a comparison between two options.

The sentence is asking which one the person liked more:

• ¿te gustó más ese personaje o el villano del final?

So the idea is:

• Did you like that character more, or the villain at the end?

Without más, the sentence would just ask whether you liked them, not which one you preferred.

This is about Spanish demonstratives:

• este = this
• ese = that
• aquel = that over there / that one farther away

In real conversation, this is not always about physical distance. It can also be about mental or discourse distance.

So ese personaje often means:

• that character
• the one we were just talking about
• the one you mentioned
• the one a little less “close” to me as speaker

An English speaker should remember that Spanish uses este / ese / aquel more systematically than English uses this / that.

Del is a contraction of:

• de + el = del

So el villano del final literally means:

• the villain of the ending/final part

In natural English, depending on context, that might be:

• the villain at the end
• the villain from the ending
• the final villain

Here final is being used as a noun meaning the ending or the final part.

Also, the contraction is required:

• de el final ❌
• del final ✅

Yes. That would also be very natural.

For example:

• Dímelo de verdad: ¿cuál te gustó más, ese personaje o el villano del final?

That version explicitly says which one.

The original sentence leaves out cuál because the two options are already clearly given. Spanish often does this in conversation.

So both are natural:

• ¿Te gustó más ese personaje o el villano del final?
• ¿Cuál te gustó más, ese personaje o el villano del final?

The first one feels a bit more direct and conversational.

The colon introduces what comes next: the speaker’s real question after Dímelo de verdad.

So the structure is:

• Dímelo de verdad: = Tell me honestly:
• ¿te gustó más ese personaje o el villano del final? = the actual question

This is very natural punctuation in Spanish. It works much like English:

• Be honest with me: did you like that character more, or the villain at the end?

And of course Spanish uses the full question marks:

• ¿ ... ?

not just the final ? used in English.
