Here's why:
* The sentence describes a past state of being, specifically referring to Jorge's appearance.
* The imperfect tense is used to describe ongoing actions or states in the past.
* The sentence is also implying a past memory, which further indicates the use of the imperfect tense.
Therefore, the complete sentence is: "Te acuerdas de Jorge? Él era muy guapo!" (Do you remember Jorge? He was very handsome!)
