Tashi was deeply asleep, so he did not instantly wake up when shaken up by Hana. He was quite exhausted after all. Once he stirred even half-conscious he lazily pulls blanket over him and groans from interruption and attempts continue sleeping. Normally he is morning person but staying wake two nights with both having intense physical activity has it's toll on his normal biological clock. Where as normal person could not able do much in second night than try stay wake.
