In this chapter, Miguel has a surprise for Esperanza and Mama, Papa’s roses. What clues were in the text in a previous chapter that might have indicated that Miguel was taking care of the rose plants?

From the text:

Her voice tense, Esperanza said, “What happened to Alfonso and Miguel?”
Hortensia pointed out the window. “They had to find some water.”
Alfonso was running toward the train with Miguel close behind, waving the secret package and grinning. The train slowly started moving as they hopped on.
