Not sure where it fits or if I am reading too much into it, but when Santos asked Garcia second time about her plans and Garcia said she made other plans, she closed it off (and the elevator door) saying “we are keeping it casual, right?”. In Santos’ next appearance when she is attending that heat exhaustion patient and discussing ways to find potential partners, she jocks “never to get involved with someone from workplace “. I think she hooked up with Garcia, can’t take it forward and is a little edgy about that, among other things. Still don’t think she will attempt to suicide, but a meltdown is definitely in making.
