Maria had honestly been surprised to see that Frank was here. The two of them hadn't had much contact since she left the Marines with an honorable discharge in 2004. Their lives had gone in different directions with him staying in the Marines while she ended up working for SHIELD. Still, she was glad to see a familiar face and one from outside of SHIELD and the Avengers too.
That was good.
Heading to the Dispatch, she found a table at the coffee shop where she could spot Frank arriving. Ordering herself a coffee, she spotted hi. "Castle!" she called out waving to him. Sure he was Frank, she would sometimes call him that but to her he was Castle and she was Hill.
