"We're not doing this in public Lena. Go home. Who is still grown? Alex? J'onn? Mon-El?" Lex asked, looking through Lena's phone, "I thought dad was dead, why do you have his number?" Lex farrowed his eyebrows.

"Oh no. She's a child again." Lillian looked at Lena sitting on a stool - dangling her legs off it.
"MoOom! Wex is twying to kill Kawa again!" Lena pointed at her brother.
"She's kinda cute, can I tape her mouth shut though?" Lex requested.
"No. We have to give her back to Kara." Lillian shook her head, "If she cries, you can tape her mouth shut though. God I hated that cry."
"Why?" Lex asked.
"Because it made me have motherly instincts." Lillian answered.
"MooOom." Lena followed Lillian, "I want Mr Snuggles. I know wou still hafe him."
"No. He's in the attic." Lillian crossed her arms, "And I'm not going up there."
Lena made puppy eyes at Lillian.
