What I liked most about Indirect Kiss was the Rose statues. Reason being, now we can see how tall Rose was in comparison to Greg.
Steven is a bit over half of Gregs height (not including his hair) and Steven came up a lil past Roses waist, that is if they were standing. Granted, Steven and the Rose statue were in a sitting position so this measurement might not be accurate, but if it is, that means that Greg came up to Roses shoulder maybe an inch or two less.
Point being, Rebecca Sugar did say that Rose was taller than Greg, but DAMN he probs had to stand on his tip-toes to kiss her, which is a very cute thought.
