Kendall Jenner calls Kylie Jenner annoying over Tyga

Kendall Jenner cannot get why Kylie cannot just have some sister time. Kendall is not impressed with Kylie's excessive obsession with her boyfriend Tyga. In an clip of Keeping up with the Kardashian, Kendall laments to Khloe as her sister took too long frolicking on the beach while she waited to do the "Fly thing" with her.
Kendall told Khloe: "It's so annoying, because I literally waited for Kylie for 30 minutes to do the fly thing,. She just took too long with T (Tyga) and and we couldn't do it, which is so annoying."
Not done, Kendall clarifies it is not even about Tyga
It's kind of annoying because I was really looking forward to being with Kylie on this trip and it's not even about Tyga, it's more that just I know she'll kinda be taken away from me."
Awww, Kylie misses her sister. The two has been very close since they were just two little girls appearing on their famous reality show. So close is (or was? ) their bond, that they have been branded together a lot in the past until recently when Kendall followed a more defined path and focused on her modelling.
There are reports that Kylie was jealous of Kendall's fame as a model as she struggled with identifying herself without Kendall. Kylie once felt abandoned by Kendall so I gotta ask. Is this some form of payback?
