Lux and Riven cross paths (assume post-retcon). What happens between them?

#Rules!

• Assume this is post-retcon lore (i.e. The IoW doesn't exist).
• No violence between the two. They have to make nice.
• Keep it in character, but don't be afraid to be a little goofy.
• No saying "They just ignore each other"; that's not what we're looking for.
