Final answer:
Jess believes Leslie will want to continue playing in their imaginary kingdom, Terabithia, even when it rains heavily.
Step-by-step explanation:
According to Jess, Leslie will still want to play in Terabithia despite the heavy rains. The reference to Leslie and Jess is from the book Bridge to Terabithia by Katherine Paterson, where the characters often escape to an imaginary kingdom in the woods called Terabithia. This magical place is a symbol of their friendship, creativity, and the freedom they feel when they are together regardless of the weather or other external circumstances.
