After the incident with the Red City, Jared and his recruit no longer dallied and left the island right away as soon as they could.
Then when they were already back to their town, Jared insisted Cassie to have a check up, in case she was hurt.
At first, Cassie declined saying she was all fine. But of course, knowing Jared, there was no way he would allow not to have things his way.
Besides, with Kyle seconding him, Cassie has no other choice but to relent.
Apparently, he too also believed that it was a right call from Jared to have Cassie see doctor in case the incident with the monster happened to have an adverse effect on her health in anyway.
Conversely, it just so happened that Aries also decided to see Cassie that day. He figured that it would be nice to check on him since he never seen her after that supposed birthday surprise.
