Hmmm, I haven't wathced that clip yet, so Im going by what FLO said, at this point.
There are still a few possibilities here...
1. maybe Jake is the one who is shot & this is the news she gets ( we don't have to see him , we could just see that Cal gets this news & freaks out, then we Jake later in the season premier.
2. maybe this news is what will make her leave for a while.
3. still, she could decide to take a break & leave at the end, then come right back next season in the first epi because of who gets shot..Natalia, H or whoever.
or if you want to be really lame...it could just be the person dead is the ME, the other person shot is just a guest star involved in the murder, & the person Eva said is leaving was just Alexx.
No excitement there, huh?
