He watched his new discovered sister then Alex clinging to her brother. For some reason he found his eyes looking back on Andy and wondering if they'd be that kind of sibling pair but with that thought, he found his face scrunching up a little, supplying his answer. It was all too clingy and protective and...they only had a mother in common. It wouldn't mean they'd bond instantly. Though a part of Daniel was very much intrigued to know about his sister and get acquainted, she had a task on her hands and mouth now. He turned his head to Alex and smirked slightly before he spoke to gain her attention. "You sure you're not poisoned anywhere?" he asked softly and manged to do so, smug free. He wouldn't mind pressing his lips to her bare skin to extract some poison. Daniel would've apologized for the inappropriate timing but it was his way of dealing with a serious situation.
When Andy spoke again, explaining the latest news on Ajax's condition and introducing herself, Daniel pressed his tongue to his cheek and nodded. He had a lot more to say to his sister but it could wait for a freer day when Ajax wasn't laying unconscious and senseless and she hadn't offered to babysit. "I'm Daniel, Andy" he tasted the name on his tongue which felt weird having to introduce yourself to a sibling but they were on ground zero and it was a start. Daniel headed out, ready to call it a night for himself as the girls were involved in some further consultation of Ajax.
Daniel wasn't sure how he felt. Kinda happy he had a sister and happy that Alex was eyeing him a lot of the time but it felt like this guy could only bare so much genuine trust and good sides, without having to manipulate or trick someone. He already had a sister and father who he did love and respect and that was enough in his books. They were honestly enough to manage.
