I've found out that when I have trouble regarding any character or any particular scene in English, sometimes I'll switch to Spanish and I'll solve the problem that I've encountered. If I'm working in Spanish and I don't know how to approach certain scenes or certain emotions, or how to say this and that, I just switch to English to try to solve it that way and it works.
