I just thought Oliver because I could see Annalise feeling responsible since she gave him a job and she might feel like he might not have been there if she didn't (and also promising to Connor that she'd keep him out of danger rang alarm bells, if he dies she'll probably feel like she's broken her promise). Also just the focus they gave him in the premiere with both the job and his breakup with Connor, TV tends to give characters more focus before killing them
